Improve host profile

[cpraveen]

I connect to our institute computers via some tunneling.

I have two computers euler and fourier, and I connect to them via xxx.yyy.zzz, and depending on port, this forwards traffic to euler or fourier.

Host nickname: euler
remote host name: xxx.yyy.zzz
Port: 2265

Host nickname: fourier
remote host name: xxx.yyy.zzz
Port: 2267

If I setup this in the visit host profiles, I can correctly connect to euler.

But I cannot connect to fourier, and if I try, it still connects to euler.

Because both have same remote host, visit seems to look in the list of hosts, and since euler comes first alphabetically, it connects to euler, even if I select fourier.

Since "Host nickname" are unique, visit should get other properties using nickname and not by using "Remote host name". That would solve this issue.
