Closes#2040 , adds test cases:
invalid bulbasaur.wc3: hidden ability
invalid charmander.pcd: hidden ability

valid leafeon: pcd mismatch -> evolved now matching
should be much easier to maintain; methods are reused with less overall
nesting
shifts encounter data from Legal's split tables to individual files for
easier maintenance and initialization. Legal Core's init is so much
simpler now.
fix resource name typo
gen5 N pkm already checked, don't flag SID
mystery gift non-eggs already checked, don't flag SID
add used DNA splicers to b2w2 permitted key item list
fix b2w2 new-altform movesets; kyurem is tricky where the form does not
exist in bw's moveset, so both indexes have to be used.
