Briefly describe the issue(s) fixed.

after messing with modules a lot, ive come up with a few changes id like implemented!

this pr makes some additions and changes to certain script events, primarily relating to modules and playstate

• module onDestroy now calls in reverse module priority order (its reverse so that modules dependent on others have the callback first)
• module onCreate is now called whenever the module is created, including after a mod reload
• modules use new IGlobalScriptedClass template (extends IPlayStateScriptedClass and IStateChangingScriptedClass) for the following:
  • new module onGameInit(event:ScriptEvent) callback for what is the current onCreate behavior, that is only called only when the game first starts
  • new module onGameClose(event:GameCloseScriptEvent) callback for whenever the game closes
  • new event type GameCloseScriptEvent extends ScriptEvent that holds the exit code
• PlayState no longer calls onDestroy in modules (only module destruction will)
• IPlayStateScriptedClass now has:
  • onPlayStateCreate(event:ScriptEvent) - helper event, called near the end of PlayState.instance.create() right before the countdown starts
  • onPlayStateClose(event:ScriptEvent) - helper event, called before PlayState does cleanup
• module onCreate will be called regardless of active (onDestroy currently does this)

Warning

this has breaking changes!!
existing modules should:

• change onCreate to onGameInit
• check for active in onCreate if any code depends on it not running when inactive
• move onDestroy code that deals with PlayState destruction to onPlayStateClose
