Add Omnibot.Module.Agent which implements the basic agent cfg + state
persistence functionality, which is then included in the Omnibot.Module.

Previously, all modules were Agents. This renames the Omnibot.Module to
be the base module, and the new Omnibot.Module uses an Agent by default.
This opens the doors to possibly allowing metamodule supervisors for
modules that may be more complex.
