Fix for this bug.

I think I've found the problem. The SVGTextElementBridge class must override
the dispose() method to unregister the listeners, but it was not doing this.

The attached patch fixes this particular memory leak bug for me.

NOTE however that there may be other instances of this kind of bug in the code.
The thing to do it seems would be to look for subclasses of
AbstractGraphicsNodeBridge that allocate resources in
initializeDynamicSupport()  but don't free them in dispose() (or don't override
dispose() at all).

In particular, does SVG12TextElementBridge have this same bug?
