Bug 1606735 - Changed heading markup where possible for accessibility

This patch excludes:
- Admin section
- H4 in the pieform since it was added to improve accessibility
- User generated page/content

Note: There are still number of pages with heading being skipped heading
especially H2. Most of the pages have H1 and H3, H1 for page heading and
h3 for sidebar panel heading. We can look into marking up sideber panels
as sections with header etc.

behatnotneeded: markup and styles changes only
