Merge branch 'serial' into server (read more)

Conflicts:
	server/server_application.cpp (resolved)

After completing the serialization code, I'm merging it into the server's
development branch. This means that although the connection and
disconnection functionality work, I still need to test the player systems
from the new server with the new serialization code.

Immediately following this commit, I'll be merging the minor tweaks to the
editor from the master branch into this one.
