Button remapping

Add the ability to have hardware buttons interact with face or do different things than Google determined. Today button remapped does this but it is a watch face thereby not allowing me to have watchmaker as a face. Adding this in would also add value perhaps put it only for paid/premium users. This should add press, double click and press and hold functions to maximize options for those with few hard buttons. It should also allow for overriding things like long hold on crown launches assistant.
