Abort and print error if window/renderer cannot be created

Browse Source 
This aborts and prints the error from SDL_GetError() if
SDL_CreateWindow() or SDL_CreateRenderer() fails.

We abort because there's not much point in continuing if the window or
renderer can't be created. There might be a use case for running the
game in headless mode, but let's code that in explicitly if we ever want
it.
