Before we implement SDL package format for DUB

[Jonathan Marler via Digitalmars-d]

I just had an "epiphany".  I believe that if I added attributes 
to ASON, it would be a true superset of SDL.  Meaning any SDL 
file would also be a valid ASON file.  What kind of monster did I 
create!  I accidently created a language that serves as both a 
superset of JSON and SDL?  I didn't think that would be possible, 
expecially with such a little amount of extensions to JSON.
