* init: rewrite init process
Now use pure globbing to generate 100% valid function and
completion paths, effectively splitting the init process in two
steps, one which paths are added, and other when initialization
is done (sourcing init).
This initialization code introduces a new interface for
`init.fish` hook, which deprecates the previously used event
model. The new interface injects three variables into `init.fish`:
path, package and bundle. This variables can be used by the
package to autoload paths, use bundled files, etc.
Also supports key bindings by sourcing
$OMF_CONFIG/key_bindings.fish and also key_bindings.fish in
packages (plugins and themes) root directories. This is done
when fish_user_key_bindings is called.

This commit adds an improved reload code for Oh My Fish, besides
saving the history now the reloading technique keeps directory
history and stack and clears fish_greeting, for a transparent
transition.
The reloading code is now safe regarding to background jobs. exec
wipes fish job control, so the user-facing code under the (just-
introduced by this commit) `omf reload` command is kept safe by a
warning. For testing purposes, `omf update` and `omf remove` rolls
automatic refresh only when `OMF_AUTO_RELOAD` variable is set.
Recap of the commit:
- Add improved reload code (omf.reload)
- Add a safe reload code (omf.cli.reload)
- Add `omf reload` command
- Add opt-in reload to `omf update` and `omf remove` commands
With great power comes great responsibility. This function is
somewhat low level, and is harmful to shell's user, as it
completely screws up with job control (subprocesses).
This PR officially marks `refresh` as deprecated, moving the
deprecated functionality to omf plugin `compat` quarantine
directory.
This updates omf plugin to new architecture, moving
functions to `functions` directory. It also revamps the
separation of concerns between CLI and underlying
implementations, organizing them into directories,
whose are autoloaded in plugin startup.
When using basename without any arguments, a usage helper as following
is displayed:
```
usage: basename string [suffix]
basename [-a] [-s suffix] string [...]
```
When listing the installed packages, if no theme was installed (e.g.
first installation), the `themes/` folder are empty and the usage helper
is displayed. This change addresses it by suppressing the message.
Since `test` interprets arguments starting with a single dash as
options when comparing `test -h = --help` just swap parameter
orders as in `test --help = -h`. Also related to issue #161 is the
issue from fish repository at fish-shell/fish-shell#2332
