Making Glock accept silencer and autolathe emaggable to build silencers

Made the silencer fit on the Glock (Glock has new typepath).
Made the Autolathe emaggable.
Emagged Autolathe can now build silencers (costs 200k metal, which means the Autolathe needs to be upgraded some).
New sprites for Glock so it can fit the silencer:

Replace with:
user << "<span class='notice'>You short out the [src]'s circuit board, enabling debug mode.</span>"
or
user << "<span class='warning'>You short out the [src]'s circuit board, enabling debug mode.</span>"

The first option makes it blue, the second option makes it red, either way it should be one of those 2 options.
