Review Request: Paint Activity

[Bryan Kearney]

Item is here:

https://bugzilla.redhat.com/show_bug.cgi?id=472071

Two things I would like folks to look at:
1) I tried a different checkout script which uses the git-snapshot 
featues. Perhaps this is a better way to bridge the gap until we get 
everything in http://dev.laptop.org/pub/sugar/sources/

2) This is my first crack at building c code in a spec file. Please 
focus on that area.

Thanks!
