[RFC PATCH] Add git quick reference

[Jonas Fonseca <fonseca@diku.dk>]

It attempts to list some of the most commonly used commands, which should
give new users an idea of how to get started.

Available both as a manpage (generated via a script) and HTML page.

 This is "ported" from the Cogito quick reference that I made (inspired
 by svn-ref) to serve as something to hand out for new users--a kinda
 cheat sheet. I don't know if git even needs another document in this
 category. However, contrary to some of the others, this document tries
 to be very brief, which might help impatient users. ;)

 Also, I am, myself, quite new to the git porcelain so any feedback on
 which commands should be included would be very much appreciated! I'd
 like to keep the format to 2 pages max, so there is still room for a
 few additions.
