SmArtKar 9cdea961cc Refactors projectile parrying and makes it actually possible. (#84973)
## About The Pull Request

Due to how projectile code currently operates its (almost) impossible to
parry projectiles and completely impossible to projectile boost them, as
they move away from you instantly after being shot. Parrying others
projectiles requires them to be slow enough and to land on a tile right
in front of you on their last move of their tick, as else they instantly
hit you.
I moved parrying component from being on user to being on projectiles
themselves and added TRAIT_MINING_PARRYING which allows users to
actually perform the parries. This allows me to get rid of parry code
existing on all projectiles and add a "grace period" mechanic - now you
can parry projectiles by clicking on any turf they moved through in the
last 0.25 seconds. Parrying actually runs when projectiles hit you if
you clicked on the correct turf during same grace period timer. This
also acts as lag compensation, allowing players with high ping to
utilize this mechanic. Projectile boosting occurs when you hit a tile
the projectile moved through in first 0.25 seconds of its existence.
Parry also occurs on click instead of attack_hand due to this, so you
can parry projectiles while holding your
accelerator/crusher/resonator(what even?) - which is also important to
make projectile boosting possible as firing sets your click cooldown -
making attacking the turf impossible (another roadblock on ultrakill
players' path)

Projectile boosting now grants x1.5 damage multiplier and +40% speed
instead of x1.15 and +20% like parrying, since its significantly harder
to perform.

Crusher projectiles now can be parried/boosted. Crushers are ***the***
badass miner weapon, but they weren't possible to boost - probably
because it'd be pointless due to their lack of damage. Now boosting a
crusher blast gives it 10 damage, +3 range and makes the mark it applies
always count as backstab for additional style (although doing so is very
tricky due to speed/range)

Crusher marks are now a STATUS_EFFECT_REFRESH effect and no longer
per-user. This means that anyone can blow up anyone else's mark and
applying new ones refreshes the timer. Trophy effects of the person who
detonated the mark are the ones actually applied.

also cleaned up pixel_move a bit

## Why It's Good For The Game

Parrying refactor - parries are a very cool mechanic which is almost
impossible to execute in-game (and boosting is physically impossible)
and even if "fixed" would require perfect server performance and single
digit ping. Making them slightly easier to execute and adding a grace
period will allow more players to utilize it and also make it possible
to do parrying/boosting on highpop.

Boosting damage/speed buff - Boosting is harder to perform, and while
with parrying damage/speed is a nice bonus to the fact that your face
doesn't explode outwards from a death bolt, for boosting its the only
reason why you'd do it (beyond style points)

Crusher boosting - Crushers are more often used by skilled miners as
they are a high risk/high reward weapon. Them not being boostable is
rather disappointing as boosting is supposed to be a thing for extremely
skilled miners to do, essentially turning crushers into deadweight for
those who wanted to use style meters.

Unified crusher marks - Mobs being able to have multiple crusher marks
made fighting very confusing for rare coop crusher miners, as you
weren't able to tell if you could detonate the mark or not. This should
make coop fighting more viable as marks can now be comboed if you have
good cooperation with your teammate.

## Changelog
🆑
refactor: Refactored parrying to be projectile-side and not user-side.
add: You can now parry crusher projectiles to give them some more range,
add damage and make the mark always count as a backstab.
add: Projectile parrying has been significantly improved, making
parrying and boosting projectiles actually possible. Includes a small
grace period as lag compensation for players with higher pings.
balance: Crusher marks can now be detonated by any crusher, not only the
one that applied it, as to incentivise coop mining for crusher users.
balance: Projectile boosting now gives a significantly bigger damage and
speed increase
