…link popup on firefox

Added search result pages for pages, chapters and books.
Limited the results on the global search as it just listed out an infinate amount.
Fixed styling on new detailed page listings and also removed the 'bars' from the side to create  a cleaner view.

This will help when adding support for new kinds of page content such as markdown as we won't be able to reference the same ID's as before thus they would break on every save.

By default DOMDocument::loadHTML treats a string as being encoded with ISO-8859-1. This causes a problem with saving cyrillic pages' text that becomes completely unreadable (like Проверка instead of normal symbols).

Updated email on users list to be a link

The new back-to-top button will show after scrolling a short distance down a long page.
Closes #44.
