Add tab completion for bash
Add tab completion for bash

Maybe this works for other shells as well.
I orientated myself at the sqlite3 completion script lying
in my `/etc/bash_completion.d/` folder.

To setup tab completion for `goto-tools` and the `goto` command,
source the goto.completion file in your `~/.bash_completion` file
by using

	. /the/path/goto.completion
