Datum Initialization Hotfix

Created by: clusterfack

Another datum pooling initialization hotfix. Initial does not actually create lists causing type mismatches after being pooled. See: http://www.byond.com/forum/?post=76850, reported to byond 5 years ago but never fixed

Causes the following runtimes: runtime error: type mismatch: += the digital switching valve (/obj/machinery/atmospherics/trinary/tvalve/digital/mirrored) proc name: build network (/obj/machinery/atmospherics/trinary/build_network) source file: trinary_base.dm,128 usr: null src: the digital switching valve (/obj/machinery/atmospherics/trinary/tvalve/digital/mirrored) call stack: the digital switching valve (/obj/machinery/atmospherics/trinary/tvalve/digital/mirrored): build network() the digital switching valve (/obj/machinery/atmospherics/trinary/tvalve/digital/mirrored): go straight() the digital switching valve (/obj/machinery/atmospherics/trinary/tvalve/digital/mirrored): initialize() the digital switching valve (/obj/machinery/atmospherics/trinary/tvalve/digital/mirrored): initialize() /datum/controller/game_control...
