Constructor should take an enum, not a true/false for udev

[whot]

libinput currently has a udev and a path interface but in the future we may have more than that. I think it'd be better if you provide a ContextType enum (or something similar) rather than the current udev=False in the constructor. Bonus - more obvious code:

l = LibInput(context=ContextType.UDEV)

I have not considered this, will do.
