VNC server

V0.22 (5/4/2020): vnc_serv.zip (203,409 bytes). Suitable for RISC OS 3.5 and above, ARMv3-ARMv8

This is Hernik Bjerregaard Pedersen's VNC server with improvements added by Crispian Daniels, David Llewellyn-Jones, and now myself.

Changes made to this version, compared to the previous:

• Removed the configuration *Commands and moved everything over to a TOML-based configuration file
• Added support for configuring the server/session name
• Added support for having multiple clients connected at once (and 'allow_exclusive', 'multiple_connections', 'broadcast_clipboard' config settings)
• Added support for listening on multiple ports (each with their own configuration)
