Title: General Improvements

`c490f804` - Moves logging from puts (stdout) to a proper Logger class (if one is provided via the LOGFILE parameter)

`d2688327` - Uses Redis' atomic features to acquire a lock around the run loop. This lets us run multiple instances of the scheduler at the same time without worrying about jobs being enqueued multiple times.

`a4cedf2e` - Add a TICK environment variable that allows you to set the polling interval from the command line.
