add experimental script engine XMRengine donated by mrieker (DreamNation) And our Melanie. ***DANGER*** ***TESTONLY*** ***disable HG*** dont leave running when not looking... tp/crossing to Xengine will reset scripts. i do see a few issues but should be testable, so we can decide if we should invest more on it.
