move logic back to cgearbackground, initialize the bg regardless of
psk/cgb input format
cache background data to return psk (potentially unintended side effects
if importing bw psk to b2w2, will have to fix cgb->psk first then undo
this tempfix)
#1699
Reduce memory usage for evo method banlist (static banlist references)
Fix gen6 mega evo flag truncation
simplify QR encode/decode logic a little
Don't apply transparency if transparency is already 100% (skip the loop)
Add gen5 wild pid/tid-sid correlation check

validating before setting the value
Fix gen3 pkm with gen4 contest ribbons in gen4/5 getting flagged
incorrectly
Closes#1236
pk4/bk4 only, obviously
side note, using static events is no-no, designer auto-removed them.
just manually reapply (as well to others that used it)
Move System.Drawing usage out of Core to WinForms, as System.Drawing is
not in .NET Core/Standard. Simple methods to return resource name
strings have been added instead.
