Section pages used to have "Section" and a number as well as the section title. Now they just have the title. Similarly for part and subsection. Closes #566.
Otherwise we have a hard-coded English string, which looks strange in ebooks written in other languages. Using the title for this entry seems a good solution. Closes #572.
Per http://idpf.org/epub/30/spec/epub30-publications.html#sec-metadata-elem, a metadata element can contain not just Dublin Core elements but also meta and link elements, but Pandoc currently strips those out. Patch from aberrancy. Closes #589.
Note: pandoc does not have an abbreviation element (yet) and so currently when this extension is enabled, it just causes pandoc to skip the abbrevation keys.
Unescaped -'s become hyphens, while \-'s are left as ascii minus signs. That is preferable for use with command-line options. See http://lintian.debian.org/tags/hyphen-used-as-minus-sign.html. Thanks to Andrea Bolognani for bringing the issue to our attention.
This seems to fix a problem viewing pandoc-generated docx files in LibreOffice.
Improved removal of markdown="1" attribute in Markdow reader.
Ext_tex_math_single_backslash and Ext_tex_math_double_backslash. Still need to code in reader.
