Fixed some error spam about a nullref in animateWoodcutting

Fixed a general script processing oversight that could cause error-throwing scripts to continue executing
Scripts being processed now automatically cancel if the interaction-target-node is no longer active (fixes object could not be replaced spam)
Fixed the stopExecuting() spam
Fixed a CME in the disconnection queue (only affected server shutdown)
Future-proofed the ground spawn parser to work with the format Zaros now outputs
Added in proper SKILLING global clock for use with the script system - addresses some quirks and brings us closer to authenticity
