Show more information in approval dialogs


Currently when you click on an approval step in a workflow you get a standard modal dialog that does not tell you which step you clicked on. Since we have multiple parallel approval steps this makes it impossible to see if you clicked the right step or mis-clicked and might be approving the wrong thing. At a minimum I would think the dialog should show the name of the step that you are approving.

It would also be very nice if you can add a description for the step in config.yml which will be shown in that dialog. This can have important information for users related to automatic deployments.
