THIS CODE SUCKS.
we need:
- contexts that aren't compared as strings,
- maybe a lookup "device,key,flags" -> actions? (lazy validation, on bindAction)
- devices as ids
- seperate native from python keys? (currently, if an action wasn't found, it's ignored.)
Sorry. I spent 3 days on thinking how this could be made better, and it just DID NOT WORKED OUT.
If you have a better idea, please tell me.
