added new tests and fixtures
Variety of improvements and additions: * Much improved list screen for elections. * Initial voter-based interface based around tokens. * New uniq_token regenerating library. Left things a little bit unstable including: * uniq_token should be refactored to provide only a class method. * voter list review page is unwritten * rankings are committed to the database but some sort somewhere seems to be botching things.
Added a series of files so that elections can be created and edited and such. There is still no functionality for running votes yet.
