brew location messages are inconsistent, confusing

[Kathy Walrath]

When you install dartium using brew in the new world, you get a location in a different format from the Dart SDK location.

$ brew install dart --with-content-shell --with-dartium
...
Please note the path to the Dart SDK:
  <path-to-homebrew>/opt/dart/libexec

--with-dartium:
  To use with IntelliJ, set the Dartium execute home to:
    <path-to-homebrew>/Cellar/dart/1.10.1/Chromium.app
...

It'd look better and be easier to document if the Dartium location was instead the equivalent (as far as I can tell) <path-to-homebrew/opt/dart/Chromium.app.

Also, do we really want to mention IntelliJ by name, when WebStorm is what we've been recommending more? Perhaps:

The Dart SDK path (required by tools such as WebStorm) is:
  <path-to-homebrew>/opt/dart/libexec

--with-dartium:
The Dartium path (required by tools such as WebStorm) is:
  <path-to-homebrew>/opt/dart/Chromium.app

This was automatically closed, but the IntelliJ question is still open.

Please re-open if we intend to make a change.
