[xmonad] Newbie first patch to make the **Ssh** extension work with user.

[Lei Chen]

Hi,

The patch add *user* support to the *Ssh* extension, .e.g ssh admin at host.
By the way, it is the first time i write haskell code snippet for a great
project. If there is anything wrong with the code, code style, comment,
 please let me know.
The *XMonad* is awesome, i love it.
