Upstream port of https://github.com/Yawn-Wider/YWPolarisVore/pull/619
Credit goes to @KillianKirilenko for this, I just ported this upstream and put all the traits in neutral.dm as per admin request!
**Description:**
This uses the universal alcohol_mod to allow for increasing/reducing the effects of ethanol based on the trait you've taken. Basically? You can get drunk more or less quickly. This does not change how fast you die when you start taking liver damage/tox, this only affects how fast alcohol makes you drunk.
