Bug 1147265 - Add filterTouches... in remaining main FF activities. r=mhaigh

GeckoPreferences inherits from GeckoPreferencesBase which inherits from
GeckoBase, avoiding Gecko, where we put the last filterTouches... so it needs
its own filterTouches... TabQueueActivity is addressed and all other activities
inherit from Gecko.
