0.9.3

New JSR223 implementation. See Jsr223TestCase for a simple example.
Contexts are not implemented yet, but bindings should work reasonably well.
Note that this is currently just a by-product, "because we can", not our main artifact.

The "baseDispatch" in the builtin types interface can now be used to add properties/methods to all builtin
objects; all dispatch tables now support simple inheritance.
