Add some documentation
Decapitalize some method parameters
relocate program language enum
test that test case is proper
move getcompatible & gettemplate to core

remove lockedslots, store & save all teamslots for sav7
differentiate locked slots from overwrite protected slots by emitting an
enum containing info about the slot
locked = can't be replaced, period.
starter/battleteam = can't be pasted over by bulk-pastes
can eventually show more specific sprite layers to denote party
indexes/team#/starter
V### names weren't enjoyable to work with; use similar verbose style as
