Added purgeSeqList function (Used in mainloop now). Let's see if this helps any...

Renamed functions:
* addScriptToList0 -> addScriptToGlobalScripts
* executeList0     -> executeGlobalScripts
* executeList1     -> executeObjectScripts
* purgeList1       -> purgeObjectScripts (Also added a clarifying TODO to this function)
* purgeList0       -> purgeGlobalScripts (Also added a clarifying TODO to this function)
