Merge pull request #13 from fedora-infra/fedmsg

Fedmsg integration
Move the index template one level up
Move the templates in the `election` folder one level up
Adjust the flask application for the new template paths
Remove the redirect.py file
Split the one controller into three

- __init__ has the main endpoints where no login is necessary
- elections has the elections related endpoints (voting, results...)
- admin has the administration related endpoints (create, edit, delete...)
Give a warning information message to admins seeing an embargoed election

And format a little the warning messages (as orange)
Make the runserver.py file executable
Remove import of the redirect file since the file no longer exists
Drop the `candidates_are_fasusers` in favor of the `usefas` field of elections1

The `usefas` field was present in the elections1 DB scheme, no need to
create a new one, just re-use the existing one
Adjust the forms and controller to use usefas instead of candidates_are_fasusers
Adjust templates for the candidates_are_fasusers to usefas change
Drop the add column candidates_are_fasusers from the upgrade sql script

The candidates_are_fasusers field is no longer needed.
