[sugar] Buildbot

[Marco Pesenti Gritti]

Hello,

I setup a buildbot master with a Fedora 9 slave.

Detailed informations on the wiki:
http://sugarlabs.org/go/DevelopmentTeam/Buildbot

Next steps:

* Setup slaves on other Linux distributions. Anyone feeling like
making one available on Ubuntu? :)
* Make the check step succeed (several pylint warnings to address).
* Automated testing (maybe we can start integrating bits of Zach work?)
* Enable mail notification on failures.
