Repositioned 'Sign Out' link to be on the end

If you have a lot of links in the navbar the admin navbar look something like this:

 [Keystone]
       Menu1 Menu2 Menu3 Menu4 
                                                Sign Out

With this it will look like this:

[Keystone]                        Sign Out
     Menu1 Menu2 Menu3 Menu4

I think its nicer this way.
