Fix generic/conventional vertex array glitches.
Changed _NEW_ARRAY_ATTRIB_0 back to 0x10000 so that the conventional and generic enable bits do not alias. In ac_import.c test Array.Normal.Enabled instead of Array._Enabled & _NEW_ARRAY_COLOR0, etc. In t_array_import.c give priority for generic arrays over conventional arrays on an individual basis, not all or none.
