Welding Tool

A welding torch can be found in storage areas or some toolboxes. 
Its uses include:
* Welding airlocks shut
* Opening welded airlocks
* Cutting through walls
* Attacking the blob
* Attacking other people
Welding torches can only carry 20 units of fuel, and need to be refuelled at a fuel tank when this has been used up.
