NSIS_TCP_Plugin

UNICODE build of TCP Plugin for NSIS that checks TCP port free or not.

Originally Created by Daniel Rejment:

I made this little plugin to be able to check for TCP ports that our server software can use. There is currently only one function that checks if a port is already in use or not, but it is useful.
