Now that the application is going to have multiple pages, vote data makes no sense
to keep with the user.
The user struct will be used everywhere to check for authentication, which is not
the case for previous votes.
Create a new struct and function in src/vote.rs to retrieve existing votes and
use them in places where user.votes was used previously.
Remove vote-related code from src/auth.rs and the week number dependence that it
required.
Instead of adding all routes manually in the Launch function for Rocket,
implement fairings for all the different files that adds the routing to
the rocket in a self-contained manner.
Previously, most redirects targeted the root of the application.
This was okay for the first part of development where only one week would be
active, but would be annoying when using multiple weeks.
Change those redirects to call week::week.
Change the login path to be dependant on the current week as well,
so it can be correctly redirected.
This first version allows login of pre-existing users, creation and update of truths
by admins, vote on the truths by users, their display as well as a simple graph
for the vote results.
Everything persisting in a SQLite database.
