Christoph Oelckers 847fa48724 - cleaned out the remaining parts of baselayer.h
In particular this means to remove the option to disable widescreen aspect ratios. The way this was handled makes no sense with the current render backend.

The aspect ratio code will have to be redone entirely to properly obey the backend's settings.
