Title: Add missing joint methods

Issue #1173 requested additional Box2D Joint methods be added. While this was pretty straightforward for most joints, GearJoint required some special treatment - in that it needs references to the constituent joints. The simplest way to approach this was to pass those joints to the GearJoint.

Since @badlogic expressed concern over how this might affect ownership/lifecycle of the joints, I am submitting as a PR for discussion.
