Merge from lp:~ivle-dev/ivle/new-dispatch.

Pretty much everything changes. Reread the setup docs. Backup your databases.
Every file is now in a different installed location, the configuration system
is rewritten, the dispatch system is rewritten, URLs are different, the
database is different, worksheets and exercises are no longer on the
filesystem, we use a templating engine, jail service protocols are rewritten,
we don't repeat ourselves, we have authorization rewritten, phpBB is gone,
and probably lots of other things that I cannot remember.

This is certainly the biggest commit I have ever made, and hopefully
the largest I ever will.
