  Add a built-in alias for 'stage' to the 'add' command

I think there's a minor user-interface defect:

    $ git help stage
    No manual entry for gitstage

"git stage" is only a built-in alias but at some point it may become the
primary staging command for new Git users and hence a kind of real Git
command. I think "git help stage" should show the git-stage manual page
(even though it only points to git-add(1)).
