Support ssh remote urls without git@

[k0kubun]

Problem

If you have an ssh config like:

Host github.com
  HostName github.com
  User git
  Port 22
  IdentityFile ~/.ssh/id_rsa

you can use some URLs which are currently not handled by open-browser-github.vim, such as:

$ git remote -v
origin  github.com:tyru/open-browser-github.vim (fetch)
origin  github.com:tyru/open-browser-github.vim (push)

$ git remote -v
origin  ssh://github.com/tyru/open-browser-github.vim (fetch)
origin  ssh://github.com/tyru/open-browser-github.vim (push)

and it shows "Could not detect repos user" to me. I personally use the first format and one of the tools I use uses the second format, so I want open-browser-github.vim to allow these as well.

Solution

I added ssh2_re and ssh3_re for these. I tried to use \%( and \) to simplify the implementation, but somehow ssh ended up captured as m[1] when I tried it. So I added them separately.
