Allow specifying a port to connect on

[TravellingGuy]

We use ssh to connect to our git server. But ssh is not listening on the default port (22), it's listening on a different port. Please add the ability to specify the port to use when entering the repository URL.

I tried to enter the repository URL like this (where 2222 would be the ssh port):
username@git.company.com:2222/git-repo
but it thought that the repository name was actually "2222/git-repo" and didn't work.
