[gpm]Syn Patch: configure buttons.

[Peter Berg Larsen]

This patch adds 

configurable finger taps:

one_finger_tap_action
two_fingers_tap_action
three_fingers_tap_action

configurable buttons press:

left_button_action
middle_button_action
right_button_action
fourth_button_action
up_button_action
down_button_action

NOTE that the 4 way button action options now have prefix four_way_*.

Adds fake_finger_layer_enabled to disable the software logic to detect
multiple fingers. (on per default)

Removed a bug that allowed wmode to be turn on even though the touchpad
did not support it.

Prints more synaptics hardware info with -D.

Rearranges and renames functions in preperation of split.
