## About The Pull Request
The title barely does justice to the content.
This PR turns a snowflake, neigh-unused, broken feature for glasses into
a rock-hard, functional, badass feature which can be applied to any
item, and also brings back the halloween screen tint, inside the pumpkin
hardhat, and also a polaroid tint for the helmet of the flash suit,
because the define was just there, unused.

for reference, the normal brightness/saturation is somewhere in the
middle. Also the pumpkin hardhat's effect is only there when it's lit
## Why It's Good For The Game
Less hardcoded implementation of the client colours for items, which
also doubles as a fix because the old code was checking for the trait on
the mob but was adding it to the item.
## Changelog
