Download output breaks ./godelw project-version

[ajlake]

I rely on tricks this like:

export VERSION=$(./godelw project-version)

This isn't reliable anymore because godel/plugin download information is sent to stdout:

{
  "version": "Downloading https://palantir.bintray.com/releases/com/palantir/godel/godel/1.2.0/godel-1.2.0.tgz to /home/circleci/.godel/downloads/godel-1.2.0.tgz...
0.0.0-9-g0083660"
}

Some ideas:

• send to stderr
• offer a -q/--quiet flag
• suppress that output when running project-version

Looks like this output is part of the godelw script itself. I think that having this output go to stderr rather than stdout is reasonable -- the output is purely informational so don't think it's important for it to go to stdout necessarily.

gradle uses the --quiet approach: https://docs.gradle.org/current/userguide/command_line_interface.html#sec:command_line_logging

I came here to report a similar issue. Just wanted to point out that in addition to the line that's being written from the godelw script, godel itself pollutes stdout some more when it's downloading plugins. The two calls to godelgetter.Download* could be updated to pass in stderr as the writer instead of stdout.
