The Hugo Front Matter contains the title for each page, it is therefore
unnecessary to include a title as the first line in the markdown. Remove
the redundant titles to clean up page presentation.

Additionally we have a number of pages that have an initial title
"introduction", "intro" or similar. These are redundant so remove them too.
