Implemented the server form. Client <-> Server interaction actually works.

Fixed a few bugs in the CustomServer - wasn't configuring the listen socket correctly, doing read/write operations from the wrong socket, etc. Reworked how the CustomConnection class handles serialization.

Added Disconnected events to the sample's CustomConnection and CustomServer classes so the forms could reset state.
