I made a choice to only log confirmed votes : there is no blank vote in the database.
This means that when fetching a user's vote, if they have not voted for everyone
there will be votes missing.
As this is sent to the templating engine via a Vector, the ordering of the votes
will be incorrect : all existing votes will follow each other, and there will be
missing votes at the end.
Update the select logic in the truth template to account for that by checking
the truth_id directly, rather than via the index of the array. (O(N²)...)
Remove 'has_vote' as this is not useful anymore.
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.
