This PR will lead us towards the Promised Day, for in its wake there shall be much celebration and ecstasy as this world becomes a world suitable for developer hegemony. The first strike is thusly;
All << is converted into to_chat().
Baymerge changed the attack proc, i think by removing a default value, and a lot of things broke because they weren't using the function correctly.
This proc does three main things.
Adds a default to /obj/item/proc/attack to target the chest when no target zone is supplied.
Fixes the lack of a target zone in many attack procs, properly defining it so it'll get passed to the parent, and ensure that bodypart-specific targeting works.
Removes most instances of code to retrieve the user's selected zone, and instead to use the zone passed into the attack function. saves duplication of effort.
