Preflight of DUB 0.9.21 (RC 3)

[Etienne Cimon]

It's worth nothing that dub.json runs as a project file in mono-d 
monodevelop IDE as well. Every dependency loads in the project 
tree. So, all in all, with git, autocomplete and everything, it's 
becoming very stable, cross-platform and beautifully integrated. 
It all makes D feel like a convenient programming language to 
use, when even 3 months ago the same dub&mono-d setup was totally 
impossible to use even though it was there. The developers on 
this are so good it seems like there's 1000s of men putting it 
all together.
