Abilities might not be 100% accurate to the gameplay yet.
update musharna's tiering

technically Musharna is now BL4, but because there isn't a BL4, I listed it as NU. as far as legality in NU and PU is concerned, this is accurate for the teambuilder and seems to be the best way to handle it.
Fix Inverse Battle
- Immunities turn into weaknesses (I don't know how I could forget that).
- Tools#getImmunity is now similar to Tools#getEffectiveness. Also add a bit of documentation, since there seems to be a lot of confusion about its usage.
AAA: Fix complex ban on Smeargle
Smeargle is banned with Prankster, rather than with Baton Pass. The later was assumed banned due to a typo in the new OP of its forum post.
Trivia plugin: refactor Trivia object and values

Fix bug in the question/answer loop that would assign undefined to
either curQ, curA, or phase, preventing anyone from answering any
questions until this.curQs was empty, by changing all of the game
variables from global variables to Trivia properties. Created a
constructor for Trivia so its methods could be kept in its prototype
object to reduce property lookup times and later to allow me to refactor
parts of the commands that deal with these properties as prototype
methods.

Fix room.addRaw not updating chat.
