Repackage HabitRPG as separate component
Expanded attributes provided by Exobrain::Agent.
Change Measurement::Geo packets to roles, not classes. Plus tests.
Ported `bee-habit` to `Agent::Action::SimpleBeeHabit`
Added Exobrain::Agent::Depends to delcare dependencies.

This is pretty neat. We can now bundle agents which will only be shown
if all their dependencies are met.
Reduce use lines in debug tools.
