=ID Properties=

This commit adds supports for per-ID properties to blender.
See http://mediawiki.blender.org/index.php/BlenderDev/ID_Property
for more information on how it all works.

ID properties are accesable by python; but note that
bindings have only been added to Object and Material thus
far. However adding more bindings is easy and I plan
on adding several more hopefully within an hour of this inital
commit.

A generic UI panel is also planned, that will go wherever its
needed; for example in the material buttons, editing buttons, etc.
I'll likely submit the initial code for that as a patch, though,
so matt and ton and others can go over it and make sure it's
all good. :)

VERY important, if you intend to use ID properties please
go to http://mediawiki.blender.org/index.php/BlenderDev/PropertyStandards
and start writing the appropriate standards for it.
