[Python-Dev] buildbot master update

["Martin v. Löwis"]

As you may have noticed: I updated the buildbot master to release 0.8.2.
If you notice any problems, please post them here.

Slave operators can upgrade their installations at their own pace;
buildbot is highly backwards compatible. As a recommendation, I suggest
that slaves run at least at the version that is available in Debian
stable (currently 0.7.8).

Regards,
Martin
