ControllerEmu: Change the GetState interface to remove range/base

Browse Source 
Do the scaling in the code that interprets the results.

This also removes the templatization of things and changes the interface
to always take a double.

This does add a bit more code to the users of GetState, especially when
having to deal with focus management, but this will be cleaned up very
soon, as focus and focus-related options will be centralized inside the
input platforms themselves, rather than spread out across all the input
plugins.
