A simple VTE-based terminal.

Termite looks for ``termite.cfg`` in ``$XDG_CONFIG_HOME`` (``~/.config`` if
unset) and then falls back to ``$XDG_CONFIG_DIRS`` (``/etc/xdg`` if unset).

Termite's exit status is 1 on a failure, including a termination of the child
process from an uncaught signal. Otherwise the exit status is that of the child
process.

DEPENDENCIES
============

A vte version >= ``0.34``. A patch is required to expose the functions needed
for keyboard selection.

During scrollback search, the current selection is changed to the search match
and copied to the PRIMARY clipboard buffer.

With the text input widget focused, up/down (or tab/shift-tab) cycle through
completions, escape closes the widget and enter accepts the input.

After hints mode is activated, as single number or a comma separated list of
hint numbers can be entered, which will be opened in the browser.
