0.9.6.1

Provisional 0.9.6.1 changes.

Restores cleanup job from 0.9.3.1, removes the most blatantly unpopular config changes, lays new ones on the table for your consideration, yanks GregTech out completely.

0.9.6.2 will be built based on feedback for these changes. I'm suspecting you might want the cleanup job for now but nothing else, in which case I can prepare a separate branch.
