Make compatible with jQuery. Slight API change. 

Rename the $() selector to $D() so that it doesn't collide with
the jQuery name.

The API change is that the 'target' option for Canvas and RFB objects
must now be a DOM Canvas element. A string is no longer accepted
because this requires that a DOM lookup is done and the Canvas and RFB
should have no UI code in them. Modularity.
