Better progress reporting during initial tool setup

On my machine, initial Haskell tool setup (after I’ve opened my first Haskell project) has taken about half an hour, and during all this time the only thing I was able to see was this spinning progress bar:

I do believe we could improve the initial experience by:

• separating this progress into stages (e.g. if, say, 7 libraries should be installed — then it should have 7 stages)
• providing more useful information on every stage (I saw that stack usually prints the total progress to the console; IntelliJ-Haskell could extract this information and draw more accurate progress)
• providing the real console output from the build tools (as I said, stack is pretty okay at reporting progress, and, as a user, I feel that I’m being “robbed” of this information by not providing me the standard console, and only utilizing this less informative progress spinner)

I use IntelliJ-Haskell 1.0.0.-beta74 build on Windows, with the latest release Stack version.

Btw, I accept pull requests 😉

Which exactly was my intention. Thanks for answer!
