This is a larger clean-up of the refresh situation. The general shift is that refreshes are now mainly triggered by the (top-level) widgets when they get shown or closed via UIManager. All refreshes for the widgets when they are in use were handled by themselves before. This adds the case of showing/closing. It is the desired result of not having UIManager:show()/:close() do (full screen) refreshes on its own.
