Add support for touch strips

[cromachina]

Depends on: #3285

I think this functionality will overlap closely with touch rings, scroll wheels, wheels/dials/paddles, triggers, or any other 1-dimensional HID, in which case maybe it could be given a more abstract name. ScrollLikeController?

This change will make the unit tester complain about every other config because I added a new config parameter "TouchStrips".

Something that could be improved is adding a way to control the speed of the invoked bindings, as this is something that the Wacom drivers also implement. It would basically be keeping track of how many times a direction was handled, and for example, only invoke on every third handling, which would make it feel slower.
