Front-end html clean-up and some functionality.
Changed URLs so that we ignore users.
Pagination is incorrectly reading all Book data.
Thumbs displayed are for all books belonging to that shelf.
Unfortunately, the content is the same on every page #.
Menus are now in base.html files.
Settings changed, you must install 'jmcclell/django-bootstrap-pagination'.
Links to another shelf work.
Some cosmetic button color changes.
Added some data to DB, not much.
Many other html changes that I don't remember.
