Use a single byte for keyswitch state

Browse Source 
Instead of having a previousState and a currentState, of which at most
two bits are used, use a single byte. This saves us a lot of code space,
and makes a number of things easier, too.

The helpers were redone as macros, since they are just bit checks now.
