If a stage is taken out of the running for Grand Prix mode and replaced with another, the rank data wasn't corrected. We were merely getting lucky that the one Round Star regularly accessible had the same number of laps as the course it replaced.
Now, Laps, Rings, and Prisons can be adjusted up or down depending on the number of each element you're expected to have with a perfect GP tally.
Related: To make it more friendly to call in multiple places, RankCapsules_CountFromMap has now been adjusted to take a course ID instead of a virtres_t.
- When a nextmapoverride is in play, do not insert the just-played map into the GP Rank
- Put all the behaviour that determines which Round icon to show in exactly one places
Also, fix a bug where it would show the skin realname for a spectating player's tally instead of the ROUND text.
Resolves most of #772.
- Match maximum size of levels array to ROUNDQUEUE_MAX, to prevent edge cases
- Explicitly check that numLevels does not equal/exceed array size before writing
