More in line with modernizing the codebase with latest c# syntax
improve web-qr decode speed slightly (no linq skiptake)
get money/coin mask without a temporary string (lol performance)
Retain a stringbuilder to mutate the string rather than finalizing temporary strings
yields some speed improvements (less gen0 string objects allocated)
Extract Species Name logic to SpeciesName
Extract Language logic to Language
Remove FormConverter wrapper for string[] fetch
Rearrange some logic to more appropriate locations, update access
modifiers / types
Move some pkm array methods to arrayutil, make generic
PKX.GetVCLanguage was a dupe of _K12.GuessedLanguage() so just expose
the method
PKX is now back to pkm data manip only
remove double string replace (now less allocations); only add up values
if they're valid numbers.
builtin int.Parse throws with "1 2", but users can type stupid stuff
like that in the program (so we parse as 12).
be explicit that the string is empty rather than possibly missing
disallow encrypted export for BK4 (they're not encrypted), removes type
check
simplify replaceall in showdownset (don't call ReplaceAll 4x, just get
valid chars and rebuild)
simplify get ribbon sprite name (precompute ToLower and appended values
