Bug 27742: Page titles have unique info first

Changed the titles of each page on the OPAC to display the unique
information first, and the name of the website (e.g. Koha library
        catalog). This is fot accessibility reasons, such as when a
screen reader user is going through tabs, they do not have to waste time
listening to the website name, they can just find the unique page title
first.

To test:
1) Go to the OPAC
2) Apply patch
3) Go to each of the pages and check that the page title has the unique
information about the page first, and the name of the website is at the
end
