Jehan ff34ec33cc Bug 791455 - Please add support for barrel rotation in brush tools. 
It turns out we already have the support since it uses the same axis as
the "wheel", used by other devices (for instance the Airbrush pen of
Wacom has a wheel reporting on this same axis).
We can't do any fancy support for this right now, but at least we can
clarify a bit the dynamics naming so that people understands it can be
used for both wheel and rotation input.
Fix the various "Wheel" dynamics strings into "Wheel/Rotation".
