[Soc-2011-dev] wiki page for developer notes

[Tom M]

Hi all, here is a page you can add notes to while learning the code.

http://wiki.blender.org/index.php/Dev:Ref/GoogleSummerOfCode/2011/NotesOnCode

Please do include a new note whenever something takes you a bit of
time to learn so we can save future coders time diving into our
codebase.
