Cleaned U\up Custom GUI, Proper Scaling, Jank Resourcre Loading

+Cleaned up Custom GUI
>Added comments to explain things
>Bike order is now Random, Placement is in the center of each quadrant
>New constructors for TronRunner for customization
+>Scaling based on cell size or auto-cell size
+>Seeds! (for Bike order during setup)
>GUI can be toggled for custom render based on boolean

+Proper Scaling
>Scaling works by defining the desired cell size, and the GUI will
auto-scale the images
>Can auto-calculate cell size based on desired frame width parameter

- Jank Resource Loading
>Still unsatisfied with how resource (image) loading is working
>Needs better organization and maybe memoization
