[FIX] Abtracts to PDF optimization

  • loading TTFonts only once
  • PDF is created in a single pass instead of three
  • TableOfContents? class is not used anymore, faster tableOfContentsEntry class is used instead
  • PDF is created from two separate PDFs, one with table of contents and second with a content itself
  • new class SimpleParagraph? added. It's much faster than normal paragraph, but has limited usability. Used in places where advanced options of paragraph like styles, line wrapping etc. are not needed.
  • layout of the PDF improved - content text and authors list are justified and some spacers were added.
  • IMPORTANT this fix needs pyPdf library, ​http://pybrary.net/pyPdf/, to merge content PDF with ToC PDF. This library is under BSD licence so, I think, we're allowed to use it.
