Adds gesture to the same group than group_gesture. Gestures
are by default isolated in their own groups.
When gestures are grouped, the state of gdk.EventSequences
is kept in sync for all of those, so calling Gesture.setSequenceState,
on one will transfer the same value to the others.

Groups also perform an "implicit grabbing" of sequences, if a gdk.EventSequence state is set to GTK_EVENT_SEQUENCE_CLAIMED on one group, every other gesture group attached to the same gtk.Widget will switch the state for that sequence to GTK_EVENT_SEQUENCE_DENIED
