ORLY - Relay commands through the hub

[FlipFlop™]

This is a protocol extension idea to allow a client or bot to send data to other users seeming to come from the hub:

client sends to the hub: HRLY <targetsid> <cmd> <data>
hub sends to targetsid: <cmd> <data>

This can be used for example to allow an external bot to send usercommands:

bot sends: HRLY ABCD ICMD <usercommand>
hub sends to ABCD: ICMD <usercommand>

[FlipFlop™]

If a client or bot is allowed to use ORLY can be based on profile of course, since it should only be allowed to be used by a fully trusted bot/client.

I have added experimental support FlexHub for ORLY, will be in next release

New profile setting 'relay' controls the usage.
Currently the only allowed command is ICMD to allow a bot to send usercommands to clients in the hub, GBot has (will have) support for ORLY and can be used for this.
