Multiplayer is playable on Linux but segfaults on exit. Need testing on Windows and macOS (need rename to .dylib?)

I have not tested extensively but I was able to connect to the 1.5 Upstream server provided by DescentMax. I flied around, shot some weapons, then exited without issue.

Unrelated to this, but related to multiplayer (#213), we will need to include dmfc.dll as a shared library in order for network loss and ping HUD elements to work properly--this may need to sync with the sever; I tried using a client-built dmfc.dll and I get crashes on join. The sever is likely using a 1.4 version of this library.
