Checks.cs initially started out small, but over the years it has grown
to handle multiple types of checks. With all these checks next to
eachother, it's hard to see the overall groups. Splitting them up
(potentially further?) allows for more focused maintenance &
understanding.
Not sure if I'm happy with the overall bandaids used (checks no longer
done within LegalityAnalysis so variable repointing is excessively
used), but I'm happier the way it is now compared to the huge Checks.cs
version was set to Encounter_XD, which did not contain the miror b
encounters.
simplify XD check to be O(1) now that version is stored in the encounter
obj
Each contest victory requires a contest participation; each
participation gives 20 OT affection (not current trainer!)
Thanks @WyrXIII , @JusLi, @Cresceda !
