[suggestion] Add option to specify a "human" name when joining.

[docwhat]

I have a separate pair account that people ssh to that joins my current wemux session.

I use ssh forced commands to force them to run a script that just runs wemux pair.

Example ~pair/.ssh/authorized_keys:

command="/Users/pairprogger/bin/pairprogger",no-port-forwarding,no-X11-forwarding ssh-rsa AAAA....

I'd like to have a human name attached to the users so when I do wemux users I can get their full name instead of the generic "pair" user.

I'd also like to be able to kick based on that human name.

I was thinking something like wemux pair --name 'Joe Cool' which would save this extra info someplace.
