Increase resolution of capsule destruction time, show time taken to clear a stage/mare
To make the latter possible in multi-mare maps, players now have a lastmaretime variable
Show the mare number in results on multi-mare maps
Always show the grade for non-special stage NiGHTS maps
Grades lower than A were hidden outside of Record Attack, but that only really makes sense for special stages, where getting the emerald is more important than getting a high score
Tweak some text colors & positioning
Replace textvar numbers with a more descriptive NTV_ enum
Fix #1121 (closed) by correcting code that still checked for capsule angle, rather than arg1
