Tidied up a few things

Main bugfix is moving the group categorisation until after everything else has tried to categorise the release. I was finding that everything in a.b.moovee was assigned to SD movies which is normally OK, but there are a number of HD releases without .nfos that were not being reclassified even though the name holds all the information necessary. They weren't then reclassified by fixReleaseNames as they aren't in the misc category. The SD categoriser would pull most of the SD movies out.

Caveat: I've not done extensive testing of this....

Also not sure if you want to include the .gitignore changes.
