Removed devise, created application controller methods to scan
for pub tickets.

Get ticket authorization and user objects working
Add instructions for creating pubtkts on command line
Refactor user population from pubtkt
Edits to pubtkt encoding and decoding
Add development sessions controller for development login
Get development login working. Fix bugs.

stuff into a warden strategy.
