With this patch, we replace cursive’s default ncurses backend with the
termion backend. This has multiple reasons:
- The ncurses backend has safety issues, see [0].
- ncurses requires a pre-installed library and a C compiler, introducing
additional build dependencies. Termion is implemented in Rust only.
- ncurses does not work on Windows, while termion works in all terminals
that support ANSI escape codes.
Per default, the termion backend does not buffer the output which may
cause flickering [1]. Therefore, we also use the
cursive_buffered_backend that buffers the output and fixes the
flickering problem.

This patch adds a new viewer, tui, that provides an interactive
interface using cursive. This viewer makes it possible to follow links
to other documentation items and to open external links in a web
browser.
This patch release adds support for documentation generated with Rust
1.45.0 and fixes some minor bugs in the documentation parser. It also
adds the documentation downloaded using rustup to the default sources.
This patch release adds basic logging output and a new `-e`/`--examples`
option to extract only the examples from the documentation. It also
fixes a bug when displaying the documentation for a function.
