Merge branch 'master' of github.com:dellsystem/mcmun-2014
Add commands for importing CCMX data

Only 5 GA/ECOSOCS (aging, untc, unhrc, afdb, icao) and ITU since each
committee had a slightly different format for the data and those 6
comprise like 2/3 of all assignments so I prioritised them. The rest
will be inputted manually.
Add CommitteeAssignment inlines to CommitteeAdmin

To make it easier for Loreena to add committee assignments manually
Add is_voting field to CommitteeAssignment
