New package namespace

This is advance warning to all users that the next release will include a move to a new package namespace: "org.scopemvc.*". (Waiting for all DNS servers to sync up.)

As part of the release I'll include an Ant script to change old code over to use the new namespace so it should involve minimal disruption.

I'm sure you'll agree that the new namespace is more convenient and "nicer" than the old one!

Thanks to our newest contributor, danmi, for prodding this change through! Expect to see lots of Swing code from him shortly. :-)
