DOSBox config changes

[Roxor128]

I've found a few issues with the game's DOSBox config. I'll be using the same comment style as the config file here.

In the [sdl] section (right near the start):

fullresolution=1920*1080 # Change this to fullresolution=auto to avoid problems on displays which don't support 1920*1080.

In the [render] section:

aspect=false # Change this to aspect=true to fix the picture getting stretched on non-4:3 displays.

In the [cpu] section:

cycles=max # Change this to cycles=auto to stop the game from running too fast.

In the [mixer] section:

rate=22050 # Change this to something higher like 44100 for better sound quality.

In the [sblaster] section:

oplrate=22050 # Change this to something higher like 44100 for better sound quality.

Thx. I changed one more line:

In the [sdl] section:
output=OpenGl # Change this to output=OpenGlnb for a sharper picture
