Gives MoMMIs a soldering iron

Created by: Gringonius

A simple change to make fixing airlocks or building them and certain wall-mounted devices less clumsy for them. Currently MoMMI needs to haul both a beaker with acid and a soldering iron if they wish to build/fix something that requires one of these board, with this change they can just load up their carried solder for about 5 boards/eletronics to be made on the spot when needed.

From my experience MoMMIs use soldering irons mainly to make or fix airlocks or in creating conveyor belts, I don't think that giving them one to their tool selection creates any sort of noticeable power creep but I'd like others to comment what they think.

Also I'm still figuring out how this works. 🎉
