Fixed most of the runtimes from the latest server errorlog.

Laser Cannon:
After IRC talk cost went up by 2k diamonds and 1k glass
Heavy version removed as it was more or less the same as the normal

Cargo:
cancelorder commented out as it is broken and throws runtimes.  I don't really have the time or will to dig though the code and fix it right now.  If anyone else or the guy who added it wants to fix it be my guest. 
runtime error: Cannot read "/datum/supply_order".object
