Provide post-installation instructions for recipes

Problem/Motivation

I tested out a recent version of Drupal CMS. On admin/modules/browse, no recipes showed up for various words, but 'forms' did show one result. I clicked 'View Commands' and a popup only had the base command: I needed to add the full path to the recipe. Be that as it may, the issue is what happened after that.

Steps to reproduce

Run the drupal_cms_forms recipe.

The output is just this:

Applied Forms recipe.
                                                                                                                        
[OK] Forms applied successfully

I then had to go to the webform listing page to find the contact form that it created.

Proposed resolution

There needs to be better help provided. RecipeRunner::triggerEvent (or whatever replaces that, if anything) should get more info from the recipe, like "The recipe was installed. To view the contact form, go to [ABC]. You can see a list of contact submissions on [XYZ]. You can add additional fields to the contact form as described at http://example.com/xyz".
