Refactoring to remove most knowledge of Redis out of the Resque::Worker. In general, trying to cut down on the number of methods in Resque::Worker and the responsibilities it has (i.e., it currently (1) gets jobs, (2) does work, (3) can tell you information about other workers on the system, (4) gets statistics from Redis, (5) acts as a Factory to find workers that are working or find a single worker, etc.)
Merging in master.
Goodbye, $TESTING.
Removing leaking abstraction with Resque::Worker using both @cant_fork in some places and will_fork? in others now that $TESTING is gone
Removes mocha, replaces with MiniTest::Stub
Merge pull request #901 from jonhyman/feature/refactoring
