Replaced the location and group selectors with a single hub selector and moved it out of the vote object block, as hub id was moved to proposals table.
This seems to have been changed to handle an improvement to a proposal, not a new proposal.  A new proposal has no parent id.  Perhaps improvements should be handled in a separate controller?  In any case, commenting this because it is unused and makes creation of new proposals fail.
Changed to refer to group instead of the older term 'topic'
