The great screen refactor

- Use vanilla's widget lists instead of custom ones
- Use press callback instead of overriding mouseClicked
- Switch old container classes to extend ContainerBase or
GhostItemContainer
- Organize foundation.gui package
- Remove deprecated methods in Color
- Various other changes
