Even with a large testing suite, all the refactoring for Wagn 1.6 left us with a few bugs, some of which had the bad habit of breaking new installations.  This release patches bugs old and new.

Three fixes in particular are key:

1. a loading error in `rake wagn:create` has been resolved
2. RSS is now validating properly
3. Several odd WQL bugs have been tracked down and squashed (see tickets for details)
