IP Setup

The port number can not be changed.
- Made a static method the checks if the port is in use, mostly so that
the IP settings feel the same as the SQL settings. I very much one to
make it test if the port is forwarded aswell.
- Stopped using FormMain_Load, because it is bugged in the debugging.
- Added an icon for my program, mostly a placeholder.
- Added a dew more message types to my protocol. Namely user creation.
