Bumped version to 1.3.3, fixed logrotate warnings, added support for Ubuntu <= 10.04

Main fix here is the logrotate_app block. If you have both server and beaver recipes in the run list, logrotate will generate errors when running because of duplicate entries for the log folder.

Also added a bit of code to support installing beaver on Ubuntu <= 10.04.

Lastly, bumped version to 1.3.3.
