Remove radio infrastructure code, along with weather and schedule app

[marekventur]

It won't work without the correct infrastructure anyway and EMF has proven that even the correct infrastructure won't get it very far ;)

The issue with the radio infrastructure was mainly due to incorrect radio clocks and lack of coverage, both can be improved for the next time.

There are also memory leaks occurring in the tilda-side badgenet code, these lockups dont seem to a
happen anymore when away from badgenet.

We should strip down to a minimal RTOS, get everything working bottom-up, then rebuild badgenet on top of it.

I have created a fork and branch which thoroughly removes the weather, schedule and BadgeID apps along with all the radio subsystems and radio datastore subsystem. I've also tried to remove all references to these subsystems elsewhere and leave in informative placeholders.

@cillian64 let us know when you're ready, I'd love to get that into master

@benjojo There was more than just coverage problems and I'm relatively sure we'll be wiser in two years time and go with something different. In the meantime the radio code is of little use to anyone and will make the code base a lot more maintainable if removed.
