Bug 27631: catalogue and tags folders

Changed each of the pages in the catalogue and tags folders to have one
<h1> tag showing that describes the page, rather than the <h1>
describing the logo.

The hierarchy of heading tags may be broken in many pages, but this
will be dealt with in an additional bug.

To test:
1) Go to the Staff Client
2) Apply patch
3) Go to each of the pages in the catalogue and tags folders and check
   that they have an obvious and descriptive heading
4) Ensure that the heading in the page is <h1>
