* 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.
Initital scaffolding of the website plus initial work on the adding and
editing general information for votes and list of candidates. The first
steps toward importing voters has also been added.
