Some code cleanup, set guide to active on rotation.  Turned off invalidate call in mousemove when there's nothing to do.

Clear menuitem now invalidates, pause menuitem text changes to reflect state.  Added show/hide menuitem and hotkey to hide guides without destroying them.  Added quit hotkey.

Moved form setup from code to designer.

Added const strings for menu text, consolidated menu calls to one function, set app name for tray icon.

Added XML commenets for everything that wanted them to satisfy tingling OCD senses
