Foam Time (#10776)

Added a mounted foam sprayer to the mechfab hardsuit modules tab. It's a hardsuit module that consumes 1500 cell charge to spray a line of metal foam.
    Added some effects to metal foam walls that make them a bit more flashy when destroyed, as well as adding a click cooldown so they can't be spammed down.
    Aggressively slamming someone through a metal foam wall now does some damage to them.
    Clicking on a metal foam wall with building materials will now attempt to turn it into a wall, taking a bit longer than a standard girder would. Clicking on it with a floor tile will now turn it into plating, if the space below is an open space or actual space.
