* Adds explanation of command lines and their arguments (gullydwarf's
suggestion).
* Switched the ``git format-patch ...`` line from using -o patches to
using --stdout. This creates a single patch file and is (probably)
easier to deal with.
* Fixed a typo.
* Adds toc to top of mediagoblin chapter
* added a YouCanHelp directive to replace FIXMEs and encourage contributors
to help out
* moved some bits around between the hacking howto and the codebase documents
* expanded on the stub nature of the theming howto
* tweaked some other text
This work is based on discussion and etherpadding (is that a verb) on
April 14th between Deb, Greg, Karen, Will, and Chris.
It was an epic collaborative sprint.
