Subject: Thank you very much, Xantor for a patch that: Copying, reseting,
 dragging scripts cause unnecessary recompilation, slowing down the simulator
 and filling up the ScriptEngines directory with compiled .dll and misc.
 files. This patch keeps track of compiled assets since the last simulator
 restarts, and only recompiles new assets. (editing a script generates a new
 asset, so no problems there).
