About The Pull Request

Ports /tg/'s connect_range component

Creates a new 'reactive_icon_update' component that allows updating an item's icon_state if a type of mob enters the specified range.
Variables:
///What we want to append to our icon_state when our conditions are filled
var/icon_prefix
///List of which directions we want to be valid. Can be NORTH/SOUTH/EAST/WEST along with NORTHEAST/SOUTHEAST/SOUTHWEST/NORTHWEST
var/list/directions
///Range that we want it to look out for.
var/range
///What type of mobs trigger the icon change.
var/list/triggering_mobs = list(/mob/living)

The format for the icon is:
initial(icon_state) + icon_prefix + _direction
ex: screwdriver_north (if no icon_prefix is set)

The above two components are currently unused, but I have some plans for them in the future.

Fixes a hard del with grabs when the user is pushed over.

Adds the comsigs:

SEND_SIGNAL(src, COMSIG_ITEM_EQUIPPED, user, slot)
SEND_SIGNAL(user, COMSIG_MOB_EQUIPPED_ITEM, src, slot)

and

SEND_SIGNAL(src, COMSIG_MOB_UNEQUIPPED_ITEM, O, target)
