Added support for LaTeX style literate Haskell code blocks in rST.
make_osx_package:  Don't hardcode jgm, use whoami.
Removed references to biblio2yaml in installers.
HTML writer:  Omit footnotes from TOC entries.

Otherwise we get doubled footnotes when headers have notes!
Added note to Interact.hs recommending 'cabal repl'.

Closes #1110.
EPUB writer:  Avoid duplicate notes when headings contain notes.

This arose because the headings are copied into the metadata
"title" field, and the note gets rendered twice.  We strip the
note now before putting the heading in "title".
EPUB writer:  Strip out footnotes from toc entries.
Increase upper bound on process.
Increase upper bound for text.
Fixed small regression in docx writer.
Added wmf and emf mime types.
Updated changelog.
Updated tests for latest texmath.
Markdown reader:  Allow hard line breaks in table cells.

The \-newline form must be used; the two-space+newline form
won't work, since in a table cell nearly every line ends with
two spaces.
Updated changelog.
Added README comment on line breaks in cells
fetchItem: Handle image URLs beginning with '//'.
Text.Pandoc.ImageSize: Parse EXIF format JPGs.

Note:  For now we just assign them all 72 dpi.  It wasn't
clear to me how to extract the resolution information.
At least the aspect ratio will be right, and 72 dpi is
the most common setting.

Closes #976.
Better exif parsing, including image resolution.

This introduces a dependency on binary >= 0.6, but we depend
on binary >= 0.5 via zip-archive anyway.

Closes #976.
Markdown parser:  be more permissive about citation keys.

Keys may now start with an underscore as well as a letter.
Underscores do not count as internal punctuation, but are
treated like alphanumerics, so "key:_2008" will work, as
it did not before.  (This change was necessary to use keys
generated by zotero.)

Closes #1111, closes #1011.
