This commit adds a forum tree YAML file (URL-based rather than an
actual tree...) and the 'forums' and 'create-forums' commands for
the master script.
A page /admin/forums is also used to currently display the forum
tree, although this will probably be turned into a full table with
forum descriptions, and a form with edition capabilities.
- remove `title` attribute
- do the migration of db
- add initialization routine in `master.py`
- add default trophies and titles in `data/trophies.yaml`
- add `add_trophy` method in `Member` class
- add `update_trophies` method in `Member` class
- add form in admin panel to give a trophy to a member
- same to remove a trophy
- change `if request.method == "POST"` to `if form.submit.data`
