Is there already a system in place for database schema migrations? I saw that you have alembic in doc/requirements-dev.txt, but there don't seem to be any migrations around. Is it already working, or in other words, is it already possible to alter models (as long as it makes sense of course)?
There was an attempt at some point, but there were no migration problems actually, so I decided to not fix a non existent problem and focus on developing the most important features (and fixing actual bugs)
But feel free to implement it.
