Rework the Button API to be saner in preparation for NativeControl rejiggering.BaseButton->Button, CustomButtonButton->ImageButtonToggleButton->ToggleImageButtonRemoving SetListener (buttons take listener through ctor)Tidy up source files. No functionality changes, just naming and organization.Look at the button classes first, then everything else.
