refactor crash

[ams76]

Hi
starting a rpractice game in the refactor branch I get this

Code:

Loaded GUI successfully
vdrift: include/loadingscreen.h:98: void LOADINGSCREEN::Update(float): Assertion `root' failed.
Aborted

I'm guessing it's caused by this

Code:

Error loading texture file: data/skins/simple/textures/loadingbox.png
Error loading graphic for loading screen.

Cheers

I've put those files into the data repository R231. Try it again.

Also, I made the game error out with an explicit message if the loading screen loading fails instead of just erroring out later with a confusing message in R2160.

yes, that fixes it.
