Changes in this version of Rogus

• Centralized library and include file location
  The library and include files are intended to be used from a centralized location. Previously, it was suggested that users put the library and include files inside each individual project folder.
• Single include directory
  There is now a single include directory for Rogus. Previously, there were four.
• Header files moved to MSVC++ warning level 4
  The Rogus header files will not generate any warnings when used at MSVC++'s warning level 4, its highest warning level. This allows users to set their whole project at warning level 4.
• Improved system for user preferences
  User preferences are now put in an object that is passed into the Rogus_McBogus constructor.
• Elimination of various globals
  These were eliminated in order to make the interface to the Rogus Library more clear. Most importantly, schedp, oap, tw, and ew no longer exist. They can be accessed via the Rogus_McBogus object. Various objects now have constructors that require a MIDI_svc*, scheduler*, err_and_warn*, or a Rogus_McBogus*. (MIDI_svc is the new name for OMS_app.)
• Removal of distinction between MidiMsg and MIDI_msg
  Formerly, MidiMsg had no "node" member.
• err_and_warn::e() no longer throws and exception
  err_and_warn is now just a reporting mechanism.
• Rogus exception type changed
  It is now Rogus_McBogus::exception or its shorter typedef, rx, rather than err_and_warn::err.
• Filedata to takes an err_and_warn* instead of a warnfunc
