Initial skeleton for adding Slot Frames
Move for logic to constructor
Frame file loads correctly
Frames show up =)
Resize bug fix for everything except the rendered map.
Numbers show up!
Different background color. Would like to eventually get an image/color here, but for now this is a fine differentiation
Centers on X axis. Good enough for now.

KNOWN ISSUES:
- Doesn't get Resize (will need to refactor this class quite a bit)
