Clean up button code to number mapping

Now BTN_MOUSE, BTN_MISC and BTN_DIGI button ranges are all mapped to the
same lower numbers including first three, corresponding to the LMR mouse
buttons. Like this:

    1       BTN_LEFT        BTN_0       BTN_TOUCH
    2       BTN_MIDDLE      BTN_1       BTN_STYLUS
    3       BTN_RIGHT       BTN_2       BTN_STYLUS2

    8       BTN_SIDE        BTN_3
    9       BTN_EXTRA       BTN_4
    10      BTN_FORWARD     BTN_5
    11      BTN_BACK        BTN_6
    12      BTN_TASK        BTN_7
    13                      BTN_8
    14                      BTN_9

This streamlines the button mapping under the assumption that these ranges
don't generally appear in a single device simultaneously. If they do appear,
they will simply report overlapping button numbers.
