Add option to disable large packages

Fixes #27

This adds the `sbruder.full` option (enabled by default), which disables
some otherwise enabled packages/modules when disabled. When setting it
to false on a full gui system it reduces the size of the system closure
by over 50%. It is intended for systems with low (main) disk space.
