config: add bar.trackpad-sensitivity

Browse source 
This is an integer that specifies the amount of scrolling that needs
to be accumulated before a wheel-up/down event is emitted.

A higher value means you need to drag your fingers a longer distance
before the event is emitted.

The default is 30.
