Improve line breaks for code
kuchiki’s NodeRef::text_contents() implementation does not take into
account the value of the display attribute or line breaks caused by br
elements.  Therefore we have to implement our own converter that
produces readable output for the HTML code generated by rustdoc.

Show links in item description
In commit 81c9cf53d6, I accidentally
disabled the links when rendering the item description.  This patch
fixes this mistake.

Add --config-file option to set custom config file
This patch adds the --config-file option that allows the user to specify
a custom configuration file (or to disable reading configuration files
if the option is set to "-").

Add support for configuration files
With this patch, we load defaults for the command-line arguments from
the configuration file located in the user configuration directory
according to the XDG Base Directory Specification.

Move command-line arguments into args module
This patch crates the args module, renames the Opt struct to Args and
moves it to the new args module.  This makes the main.rs file easier to
read and allows us to add more details to the Args struct in the future.

Add --no-syntax-highlight and --theme options
This patch adds two new command-line options for the rich text viewer:
--no-syntax-highlight and --theme.  --no-syntax-highlight disables the
syntax highlighting for code snippets.  --theme selects a color theme
for the syntax highlighting.

Pass viewer args to viewer implementations
This patch adds the ViewerArgs struct to the Opt struct that contains
the viewer-specific arguments.  It also adds a ViewerArgs argument to
the methods of the Viewer trait so that viewers can access these
arguments.

We also refactor the TextViewer implementations so that we can pass the
viewer arguments to the Printer constructor.

Currently, there are no viewer arguments, but we will add them in
upcoming patches.

Print definitions as code instead of HTML
Previously, we renderer item and member definitions as HTML.  With this
patch, we print them as code so that they can be highlighted in the rich
text output.

Add syntax highlighting for code snippets
This patch uses syntect to add syntax highlighting for code snippets in
the rich text output.  Currently, this only applies to the examples
printed with the -e/--examples option.

Wrap HTML and plain text in Text struct
This patch adds the Text struct to the doc module that is a wrapper for
a string that is available as HTML or as plain text.  This makes it
clearer what data is stored in the Doc and Example structs and what the
viewers should do with this data.

Release v0.1.3
This patch release adds support for documentation generated with Rust

Fix list of methods for Rust 1.45
As described in the previous commit, Rust 1.45 changed the ID of the
methods subheading from "methods" to "implementations".  The last patch
fixed this for the trait implementations, this patch updates the method
group parser with the new IDs.

Fix trait implementation list for Rust 1.45
In older Rust versions, trait implementations were listed under the
heading with the id "implementations" and in the div with the id
"implementations-list".  Since Rust 1.45, the method heading has the id
"implementations" and the trait implementations have the ids
"trait-implementations" and "trait-implementations-list".

This patch updates the parser with these new IDs while also checking the
old IDs for older documentation.

Extract description of module items as HTML
Previously, we only showed plain text versions of the item descriptions
in the module overview due to a formatting issue.  As this issue
disappeared, we can now use the HTML version of the description.

Show definition for constants
Similar to the fix for functions in 1a242e5, we have to use a different

".docblock.type-decl".

Remove spurious members from module documentation
With this patch, we require that the identifier element for a member in
the module documentation is a direct child of the table cell.  This
fixes problems with spurious member elements if there are more elements
in the table cell, e. g. stability annotations.

Fix definition for methods in documentation parser
This patch changes the documentation parser for methods to use the first
code child of the subheading as the definition instead of the first
child.  This fixes a problems when there is additional information in
the subheading, for example about the relevant traits.

Use rustc --print sysroot for default sources
Previously, we were used /usr/share/doc/rust{,-doc}/html as a default
source, assuming that it would contain the standard library
documentation.  This is true if the user installed the Rust
documentation manually or using a package manager.  If they use rustup
instead, the documentation is placed in a subdirectory of ~/.rustup.

With this patch, we call `rustc --print sysroot` to determine the
installation directory of the currently activated Rust toolchain –
either the system Rust installation or a Rust installation managed by
rustup.  We then use `$(sysroot)/share/doc/…` as a default path for the
standard library documentation (with /usr as a fallback if the call to
rustc does not return a valid path).

Add -e/--example option to only show examples
As requested here [0], this patch adds a new -e/--example option that
extracts the examples from the documentation string instead of printing
the full documentation for an item.  Syntax highlighting will be added
in the future.

Fix definition selector for functions
Previosuly, we always used the selector ".docblock.type-decl" to select
the definition for an item.  But this did not work for functions.
Therefore we change the selector to "pre.fn" for functions.

Format text output look like man
With this patch, we change our rich and plain viewer implementations to
format their output similar to the output of man.  This means:
- Adding a title with the current crate, documentation item and
  “rusty-man”
- Printing headings at indent levels 0, 3, 6 and printing content with
  indent 6, 12
- Printing headings bold and uppercase (level 1) or bold (levels 2, 3)
