rund users welcome

[Jonathan Marler]

I've rewritten rdmd into a new tool called "rund" and have been 
using it for about 4 months. It runs about twice as fast making 
my workflow much "snappier". It also introduces a new feature 
called "source directives" where you can add special comments to 
the beginning of your D code to set various compiler options like 
import paths, versions, environment variable etc.  Feel free to 
use it, test it, provide feedback, contribute.
