Basic domain locking, debug hotkeys

Game should now display a black screen (ie: it never boots up) except
when a) run from quarterspiral.com or b) compiled with CONFIG::DEBUG set
to true
See Startup.as for the code that controls this business
Also, removed "S" and "M" hotkeys from release builds.
Misc: Boolean warning removed

Changed 0s & 1s to false's and true's in XpBar.as to fix minor
FlashDevelop compiler warning
