svn repository move

Heads up! In the short term, parrot's svn repository will be relocating from perl.org to parrot.org.

When this happens, there will be a small amount of downtime, and after that you'll be able to keep working with a simple 'svn switch' in your checkout.

We were going to try to squeeze this in today, but that's been postponed. More details on the schedule as they become available.
