Uses a mob var to determine antag validity instead of typechecks, since I believe this will work out better in the long term. Inheritance can automatically make new mobs we make be invalid by default.
Adds a fairly simple system that allows adjusting various numbers like max health, incoming damage, outgoing melee damage, etc. The nice part is that changing certain variables this way (like max health) is a lot safer than manually setting the max health var directly.
Changes a lot of short lines of code to point towards a variable's getter or setter helper instead of reading the var directly so the modifiers can work.
Endoarmor, delayed toxin sting, Enfeebling sting, and recursive adrenaline overdose now use the modifier system.
Enfeebling sting now only lasts two minutes, from five minutes, however it now also reduces the victim's melee damage by 25%/50%, and increases the damage they suffer by 10%/35%, for normal and recursive respectively.
Delayed Toxin Sting's effects are now felt all at once instead of over the course of a few minutes.
Merges the use of the is_small and mob_size into one.
Changes the species size handling to set the mob size instead of being yet another separate var to check.
Updates Bump() code.
Intents now use constants.
Simple animals can now use languages without overriding say().
There is now a difference between being able to smash normal and reinforced walls.
Reworks simple_animal/attackby so that constructs don't need to override it simply to add damage resistance.
