XCode proj: experimental default compiler bump
Made location of .scons-option-cache modifiable from command line.
Add a new TC shade ("Bright green") and apply to the unmoved orb

Use the leader ellipse
Use hero ellipse alongside hero crown

The adding of the Windows tray notification enabled this event on
