AltForm & Form & Forme => Form
GenNumber & Generation => Generation
Extract out SpeciesForm interface, and re-add IGeneration
For those using PKHeX as a dependency, this should be a pretty straightforward manual replacement... GenNumber and AltForm should be quick find-replace`s.
Closes#2826
It doesn't find it in the SM table, but didn't return -1
rework logic flow to return when found, rather than after loop finishes.
Also fix display off-by-1 since we're not using zero indexing for our entry numbers.
Thanks @Ammako !
