Improve multi clients mode : allow enabling further connections and setting connect-id
Improve multi clients mode:
- Allow master client to enable/disable further connections from collaboration panel. Default is enable.
- Add option --disable-further-connections on server to disable further connection by default.
- Allow master client to change server connect-id from collaboration panel.
- Add popup to ask user for connect id when client try to connect to server with a wrong id.
