Request: Don't dispose a GameScreen when Loading another so that a "background" screen can still be in the Update-Loop

[Mephisztoe]

Sometimes, it makes sense to update whatever happens within a GameScreen, even if you leave it. GameScreens can be used not only to have a LoadingScreen, a MenuScreen, a MainScreen, a HighScoreScreen, etc... but also within an RPG Game for instance to create different Rooms. However, when leaving one Room, it could make sense to have another room still be updated in the background.

I am aware of the fact that this might lead to other issues (such as memory consumption and the question about which GameScreens to leave intact and which to dispose), but this is something the developer mus understand and be aware of.
