A dirty module to manage school related roles and channels

[czechbol]

I don't know what to do with this one, it isn't great but it worked fine. We merge it? Keep it a draft?

I'd prefer if
1/ the module had an example files,
2/ had a README describing what it does and what are its limits.

With a fact that we only need this once a year of less, I'd be ok merging this.
