my first kernel in betterC D

I spent a few minutes on just turning the C code to betterC D - 
was curious to see if it would work.  It seems to.  I didn't try 
loading with GRUB.  The dub.sdl isn't quite right, so best run 
./build.sh

Cannot push to code.dlang.org - it complains about registering a 
forked package, even after renaming.
