Update edit actions to match 3.1 styles

Moved the workflow buttons into the major actions group for 3.1

I think it would be nice for the button to reflect the actual action you are performing [approve, reject, et al] . You could do this in a few different ways. The simplest would be to change the name of the button when the dropdown is changed. A better option would be to remove the dropdown and reference the actions directly. Maybe something like this:

However, I wouldn't know enough about how workflow works to implement that. And it has it's own problems (approval is itself a major action, and this route makes it appear less important). I do feel that having the two things disconnected as they are now is a bit of a usability issue though.
