Make the IM and friends modules optional. Clean up some code that dealt

with the old Grid Instant Message over OGS1. Refactor the EventManager
to be independent of the rigid module structure design imposed by
the current implementation. Message routing is now done in the destination
module rather than in the event manager. This way, more or less granular
solutions are possible without core changes.
