Changed this function's name, because it confusingly only calls
DetermineLinkBattleResult when linked through mobile.
It does absolutely nothing with determining the battle result in a
regular link battle, and is only responsible for displaying the battle
result and counting stats.
The UbersCheck and LevelCheck are used only for the battle tower,
despite them living in the mobile files.
Also labelled some of the known BattleTowerActions.
Just keeping things consistent. Nobody's going to write SELF_DESTRUCT.
Kind of subjective, and we could do it the other way around, if anybody
really cares.
There were a lot of unused labels in there, and a few confusing
misnomers around move_effects_pointers.asm. They now match up exactly
with the names in battle_constants.asm.
Also renamed a few effects, to make their purpose clearer, and to match
up with their respective event script commands:
EFFECT_EXPLOSION -> EFFECT_SELFDESCTRUCT
EFFECT_HAZE -> EFFECT_RESET_STATS
EFFECT_WHIRLWIND -> EFFECT_FORCE_SWITCH
EFFECT_BIND -> EFFECT_TRAP_TARGET
EFFECT_TWINEEDLE -> EFFECT_POISON_MULTI_HIT
EFFECT_STEEL_WING -> EFFECT_DEFENSE_UP_HIT
EFFECT_METAL_CLAW -> EFFECT_ATTACK_UP_HIT
EFFECT_ANCIENTPOWER -> EFFECT_ALL_UP_HIT
A few projects I looked around in used these same labels for these
functions, and it looks like they describe these functions properly.
Also fixed usage of BANK() in a few places.
WATRTILE was wrongly defined as 15, and WALLTILE as 1. Those had to be
flipped around.
This has allowed for us to replace inmediate values with these constants
in several places to improve readability.
WATRTILE was renamed to WATERTILE in the name of readability.
