Had this one hanging around from like a month ago...

Added the ability to set the geometry comparators
for the buckets for those cases where the app may
know better.

/**
* Sets a different geometry comparator for the specified bucket, one
* of Gui, Opaque, Sky, or Transparent. The GeometryComparators are
* used to sort the accumulated list of geometries before actual rendering
* occurs.
*
* <p>The most significant comparator is the one for the transparent
* bucket since there is no correct way to sort the transparent bucket
* that will handle all geometry all the time. In certain cases, the
* application may know the best way to sort and now has the option of
* configuring a specific implementation.</p>
*
* <p>The default comparators are:</p>
* <ul>
* <li>Bucket.Opaque: {@link com.jme3.renderer.queue.OpaqueComparator} which sorts
* by material first and front to back within the same material.
* <li>Bucket.Transparent: {@link com.jme3.renderer.queue.TransparentComparator} which
* sorts purely back to front by leading bounding edge with no material sort.
* <li>Bucket.Sky: {@link com.jme3.renderer.queue.NullComparator} which does no sorting
* at all.
* <li>Bucket.Gui: {@link com.jme3.renderer.queue.GuiComparator} sorts geometries back to
* front based on their Z values.
