Add language agnostic Auto-Format

Auto formatting is a great aid in writing code as it helps keep things clean and easier to read. When dealing with larger functions and conditionals, it becomes even more important as proper indentation is the best visual cue of where a code block starts and where it ends.

In Gedit, it is possible to use the External tools plugin to get Vim to auto format any piece of text. The specification URL links to a tutorial on the script used for Gedit, which is essentially parsing the text through Vim and its powerful formatting options.

This command should have an easy shortcut, preferably one-handed, like Ctrl+T.
