Title: Adds support for reviewing proposals in groups.

In this scheme, each group has it's own start/stop times for leaving speaker
comments and doing voting.

Additional work to come with more utilities for working with groups (e.g.
auto-assignment of proposals to groups).

For now this should be stand-alone though.
