Clean up UI for scenario trigger and step plugin components

I just developed scenario trigger and scenario step plugin components for the first time and really appreciate the ability to create these.

However, the UI for these could be improved.  See screen shots below for reference.

Two requests:

  1. Only show the component name once. Currently this is shown twice.
  2. If the plugin URL is blank don't show the "Learn more" link. In the many cases the explanation that we are able to include directly in the UI is sufficient for people to understand what to do. In these cases there is no need to specify more information at some URL.  If no URL is specified the "Learn more" link brings up the home screen which is confusing.
