dub with VisualD

[Patrick Schluter]

Just a dumb question, how does one use dub with VisualD? I have a 
project that compiles without issue with dub. It has 2 
dependencies, dxml and dwt.
dxml is no problem, dwt is a bit bigger. Dub has no issue to 
download and compile it.
With Visual Studio I was not able to instruct the IDE to either 
take the dependencies from the dub.json or to call dub to build 
the program.
