VNC tweaks

There seems to be a bug in the host which prevents re-connection after disconnection. Nothing is printed in the log, but client complains "Failed to receive data from socket." If I close the client, and try to connect back again.

My vnc client has clipboard synchronisation, and it looks like that the implemented VNC client supports it. See Received cut buffer:

[D][vnc:294]: Accepted x.x.x.x
[D][vnc:650]: Read RFB 003.003
 as version
[I][vnc:666]: Client requested authentication 1
[D][vnc:563]: Read 11 encoding types
[D][vnc:623]: Received cut buffer My vnc client has clipboard syncronization
[D][vnc:623]: Received cut buffer  and it looks like that the implemented VNC client supports it. 

[W][vnc:632]: Unknown command 97
[W][vnc:632]: Unknown command 99

However it's of little use here so I'd suggest to disbale it. Seems like certain copied texts are interpreted as commands which may lead to potential issues.

Fixed, this is merged into the lvgl branch.
