Opted to go with this at the top of each of the successive sections that require the keyserver to be running. If it's too wordy, we can provide a link to the "Running keyserver" section or another alternative. But this information helps someone who just looks at/searches for the "Running web app" section without reading any other parts of the document.

This was pushed down from the "Running keyserver" section because it makes more sense here. The web app cannot be viewed in the developer's web browser until:

1. The keyserver is running
2. The web app is running

Thus, by moving this statement below the code to run the web app, it now more accurately represents what's running.

This was added to match the similar paragraphs in the below sections. The paragraphs in the "Running web app" and "Running mobile app" sections both say "This command..."

This was pushed down from the "Running keyserver" section because it makes more sense here. The landing page cannot be viewed in the developer's web browser until:

1. The keyserver is running
2. The landing page is running

Thus, by moving this statement below the code to run the landing page, it now more accurately represents what's running.

This was something I must have missed in D4257, I'm not sure how. Fixed it here because it's a really quick change.
