* Add an automatic job every day at 4 AM to recompute the progrank of
every program. Currently everyone gets progrank 0.
[MIGRATION] This commit contains a new version of the schema.
[SETUP]
* Install flask-crontab (with pip)
* Run `flask crontab add` to register the jobs
* Add a TagListField which automatically validates its input against the
TagInformation database, and has a richer .selected_tags() method
* Add a dynamic tag input widget, available through a macro (*import
with context*), that supports both JS and non-JS input
* Add a TagInformation.all_tags() function
* Add colored tag display to all themes
* Fix a bug causing programs to have no names
* Add tags: games.action, games.narrative, courses.informatics
[MASTER] Run the 'update-tags' command of master.py.
Not tested yet since there is a lack of tools to manipulate comments,
topics and programs. The /programmes routes is used to display a list of
all programs, temporarily.
