Kepler

This is a tracking bug meant to ensure that the standard kepler 2.0 system provides everything needed by modules.

We'll attempt to anticipate needs by at least making 2.0 provide everything needed by modules under development now, like wrp, comad, master-slave, etc.

For example, the configuration system should be in place (bug #3948), potentially a centralized event bus for module communication (although it's been suggested that modules should provide and listen to these interfaces themselves instead), and so forth. Please add blockers here as you encounter them.
