Making a screen manager and solving the problem of logs NPE'ing in tests
Some quick documentation
Using screen manager and fixing tests/code to actually go back sanely =)
Technically, going back works. But node screens are somehow eating that. Suspect that something above it is eating the thing, or the reset is somehow eating it.
Makes more sense (but is harder to test this new bug)
Adding much more logging around listeners to try and figure out what's wrong.

You can go back now, but going back makes the screen unusable. Screen architecture needs a pass to make it more modular/reloadable from memory
Blam. The input processor never switched when moving stages. for now, putting that in resize. Fixes #448
