Some classes could be separated from Node extends

[valkyrienyanko]

For example the class LevelUIManager extends from Control. This isn't that great because it would be nice if this was a static class but since it extends from a Control this is currently not possible. The perks of this being static would make it accessible anywhere and show only the methods and properties that matter as suppose to seeing a cluster of methods from Control hiding the methods that really matter.

Same idea applies to TransitionManager and UIConsoleManager

All of these classes will never have more than one instance.
