Unloaded mapheader record tracking: Manage memory usage by dropping unimportant stats

Browse source 
Only persist the full data while unloaded if player has explicitly achieved something on that level, rather than merely visited (such as in a netgame).
Achieving something counts as:
- Getting a best time
- Getting a best lap time (Race only)
- Getting MV_SPBATTACK (completing an SPB run)
- Completing the level IF the level has LF2_FINISHNEEDED (finish level in GP/MP before you see it in Time Attack)
