* Uses LearnSource more throughout the codebase when appropriate, rather than loosely coupled pivot methods. * Hides Learnset/EggMove data inside the LearnSource classes. * Extracts functionality from the large Legal class & partial Table*.cs files into better performing helper classes. * Cleans up some code from prior LearnSource commits.
