Some testing fixes.

Added a online category to some tests which require online access.
Saved a copy of CKAN-meta-testkan.zip so that the sanity checker tests are offline.
Fixed KSP.Training test to work on windows as well as linux.
Okay, I don't know all the service UUIDs off the top of my head, which one is `82A7F48D-3B50-4B1E-B82E-3ADA8210C358`? ;)
