js/ui: Subscribe touchpad gesture handlers to only touchpad events

Browse Source 
The touchpad gesture handlers were receiving all events, all the time.
This meant that even mouse movements were getting translated into
JavaScript calls and then discarded by the handlers, which wasted CPU.

Now we subscribe the touchpad gesture handlers to only touchpad events.
