other items now spawn. not confident about the spawn rate being equal (small samples).

- cameras are wonky, rendered world is small. look at old code for if renderer had its own camera
- item listeners not doing anything (seemingly)
removing unused imports

Camera doesn't need to be attached to worldStage, but needs to move from there.
I think this line moved might be the lag culprit, too; it only needs to call when changed, not when rendering

Thinking more clearly about these cameras. Renderer needs one, Game Stage needs one. UI does not.

Items move again, but not the BG...

Items are clickable. Multiplexer in place. Items/Gameworld moves.

KNOWN BUGS AT THIS COMMIT:
- renderer camera isn't moving it
- do cameras need to change in resize?
BG/renderer camera moves now. These methods are apparently vital to be in render. Makes sense now.
