Changed configuration keywords
* src/core/stream.py
  -- Instead of dumping module configuration each time something
  is entered, we now instead display it once on startup.  If the user
  woudl like to verify settings before the module is run, they may
  enter "ops", which will dump the local module options.
* src/core/util.py
  -- Changed "opts" to "gops", whcih is short for global options.  This
  allows us to use "ops" in the context of a module.
