Cocoa: Send correct mouse buttons for tablets

Browse Source 
Tablet vendors allow user configurable pen buttons
where the user may assign a logical mouse button to
a given physical button.

In the case of Wacom tablets this mapping is not reflected
in the buttonMask API, which returns the state of
the physical buttons.

Use NSEvent buttonNummber instead, which returns the
logical button number, after applying user mappings.
Unifiy button state stacking with the mouse handlers.

Handle a special case where buttonNumber returns 0
for tablet right mouse presses. We get these events
via rightMouse* event handlers and can hardcode the
button number.
