Delays and samples are not implemented yet and thus the tests are skipped, as these require parsing the delay and sample tables also. Various macronames were changed to be more sensible and consistent i.e. ATTAC was changed to ATTACK. GatesLow and GatesHigh was removed for the time being and the tracker will just have to know they are the SHAPE and COLOR parameters. SU_SPEED was changed to take a parameter so the parser picks it up.
