* Unified EFFECT_RECOIL
Combined EFFECT_RECOIL_25/33/50/33_STATUS into a single EFFECT; added an extra field to BattleMove 'secondaryData' that contains the franction of HP recoil; argument still holds status effect for Flare Blitz/Volt Tackle
* BattleMove struct change
Added critrate, recoil, multihit fields, made zMove into a union of effect/powerOverride for status/non-status moves respectively. Added new recoil field and zMove field to all moves. To-do: crit rate, multihit
* Critrate field added
Moves use a critRate field instead of a flag - obsoletes EFFECT_ALWAYS_CRIT
* Just a little define
Makes clear that critBoost = 3 means ALWAYS CRIT
* Added a proper recoil field
Just to make it unambiguous and flexible - can finally have a move with 69% recoil.
* Fixed AI damage calculation for multi-strike moves
* Fixes + removed unused effects
* Tests fixes
Two to fix: pass when run in isolation but not when the whole group is run, which is annoying...
* Minor fixes
* Minor tweaks
* Fixed move effects
* recoil tests
