main() has been replaced by init(), enable() and disable()
when disabling, all sources and notifications associated with gajim
contacts are automatically closed
Extensions that use public Shell API are expected to work for all
stable 3.0 releases, so we skip setting the minor version. (This
means that they'll work in 3.0.0 and 3.0.1 without rebuilding).
Notably absent are auto-move-windows and windowsNavigator, that
hook deep into Shell code and could be broken by next minor release.
