[Controversial] Attacking turf with a weapon will attack the person on it

[Crystalwarrior]

To explain simply, when you click turf/decal with a weapon in-hand, you will hit the mob. This effectively turns a person's hitbox into 32x32 tile, eliminating the inconsistent hitreg based on different clothing, etc. and making it overall a bit more reliable to hit people (if you intend to attack them in the first place).
This will only affect weapons with force > 0 and/or stamina_damage > 20. Punches are unaffected (for now?).

Note that THIS IS LARGERY UNTESTED save for single-player monkey-beatings. To properly balance, fix and implement this patch it will need to be tested on a test server with a few people first!

The purpose of this patch is to eliminate a bit of the clickspammy factor and make misclicks less punishing for such tiny hitboxes (unless they're fat as shit or wearing a lot of things/a backpack/etc.)
