Merge pull request #1 from christianwach/master

some modifications to the print styles
modified CSS style for ZotPress biblio entries
modified header_body and styling

on mobile devices, bottom area lists "Contents, Read, Discuss" rather
than "Navigate, Content, Discuss" (to avoid confusion between
"Contents" and "Content")
modified order of items in toc sidebar

changed to "Chapters, Special Pages, Search" from the original "Search,
Special Pages, Table of Contents" (to avoid redundancy and emphasize
chapters to be read)
manually added Christian's pull req to remove bottom padding from TOC
