Git documentation reorganization and cleanup

[Sandy Armstrong <sanfordarmstrong gmail com>]

Hi all,

Just a quick note that I've been working a bit on cleaning up our git
documentation.  It is now centralized here:

http://live.gnome.org/Git

And the main developer howto has been simplified.  It now recommends a
single simple workflow of hacking, making a single commit, and
generating a patch using `git format-patch HEAD^`:

http://live.gnome.org/Git/Developers

I really want to keep this page comprehensible for new contributors,
as much as we can.  If you have ideas for how to improve it, any help
is welcome.  Please keep in mind that I'm actually pretty new to git,
and may not be aware of better workflows for new contributors.

I'd like to add Git/FAQ and a page about workflows and/or branching
strategies, as well as how to share branches via gitorious, github,
etc.  If anyone is interested in this, any content is better than no
content.  I'd rather see a FAQ full of unanswered questions than a
blank one.  :-)

I'm also particularly interested in having good documentation for
Windows and Mac users, so if anybody is already working on something
similar, I'd love to hear about it.  Let's try to keep our git
documentation under l.g.o/Git/.

Best,
Sandy
