Added "splat" to Utilities. This writes out larger items as tab-separated-values files, which saves overhead of Dumper. Update slurp to eval then split on newlines and tabs (i.e., handle splat output).
Execution front end for schedules. Main use is tying together the various modules used with S::D for running a set of jobs. Exports "runsched" to pass in the schedule and optional sequence of schedule items to debug for #! code.
