Updated remaining Primal Weathers to the new APIs.
Updated misleading test cases relating to base power of moves in
Desolate Land / Primordial Sea.
Increased coverage on weather tests.
The unwieldy system that is typesData is now removed, and is replaced by
the array `types` and the string `addedType`, which track the same amount
of information in a much more efficient way. (Roost is now hardcoded, but
let's not talk about that.)
Incidentally, this now roughly matches client, which tracks typechange
and typeadd as volatiles.
This allows us to remove ModifyPokemon, which overall provides a 10%
performance increase. I was hoping it'd be more substantial, but oh well.
Add new function battle.insertQueue that inserts a decision into the
correct position in an already-sorted queue instead of re-sorting. Also,
to prevent code reuse, add new funciton battle.resolvePriority to deal
with shared code between battle.addQueue and battle.insertQueue.
