Title: Finish of a.close to button.close

In 2.0.3-wip a.close changed to button.close in most places with a disclaimer that a.close could still be used with href="#" for iOS support.

This commit finishes of that conversion of the docs so that it doesn't get confusing why a is used sometimes and button sometimes.
