Fixes HTML files generated from ADOC sources by the Maven site and Asciidoctor plugins. The problems fixed are:

*add a text to the HTML title of the page (empty otherwise) * add text to the active bread crumb list item (empty otherwise)

This function will take the file name (first argument, no extension) and use sed to add the text from the second argument to the HTML file. For the title, it assumes that there is a prefix in the title, so it adds x2013; $2.
