Botond Ballo f7282ab158 Bug 1217515 - Clean up the way touch event support is configured. r=roc
- all.js now sets dom.w3c_touch_events.enabled to auto-detect on all
  platforms except windows and mac
- auto-detect always returns true for android and b2g
- graphene and tests override the all.js pref with their own value
