hookup_manager stage one:  New tables for pending and active hookups (pair programming events).  Pivotal #75025008, 75025492

relates to pivotal stories "display list of pending events in a table", 75025008, and "display list of active/live hookups (i.e. hookups with live hangouts) in a separate table",75025492. 
@yaro: This table will most likely change in the near future, and there's a good chance that the active and pending tables will diverge more.  For example, the active events may display links for join and manage hookup, vs. start hangout and possibly "intend to join" for pending, and the time column may show actual start time (active), vs. planned start time (pending), and more.  So I think that the costs outweigh the benefits, especially in the long term, for extracting this into a common partial.
