Rough first pass of division edit functionality
Make second-level nav on division page work without JS. Fixes #117
Display all the different long party names on the votes table
Display correct class on vote table
Also support free votes
Also cycle the class on the other vote table
Well this is weird - display user's active policy in division links

Except not on some links. For some unknown reason.
Test updating division name and description

Still failing thanks to #166
