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.
Fix client crash from 072d413

Send 'trapped' flag in requests for pokémon that are known trapped
- Implement BattlePokemon#isLastActive to do the check for whether this is the last non-fainted active pokémon in a team.
- BattlePokemon#tryTrap now accepts an argument that, if true, will hide the fact that a pokémon is trapped.
- This should revert an small (annoying) change in the UI for locked moves introduced as a secondary effect in 8afc588e4.
- NEXT: Shadow Tag shouldn't activate the 'maybeTrapped' flag after the suspected Shadow Tagger has made a move.
