INSTALL: Added instructions for pandoc-citeproc.
Merge branch 'master' of github.com:jgm/pandoc
Updated changelog
Factored out registerHeader from markdown reader, added to Parsing.

Text.Pandoc.Parsing now exports registerHeader, which can be
used in other readers.
Use registerHeader in RST and LaTeX readers.

This will give automatic unique identifiers, unless
`-auto_identifiers` is specified.
Use registerHeader in Textile reader.

This produces automatic header identifiers, unless `auto_identifiers`
extension is disabled.

Closes #967.
Document fact that --toc doesn't do anything for docx or odt output.

See #458.
Mathjax in HTML slide shows:  include explicit "Typeset" instruction.

This seems to be needed for some formats (e.g. slideous) and won't
hurt in others.

Closes #966.
Markdown reader: Don't autolink a bare URI that is followed by `</a>`.

Closes #937.
Added `--metadata/-M` option.

This is like `--variable/-V`, but actually adds to metadata, not
just variables.
Restore --bibliography, --csl, --citation-abbreviations.

These are now implemented as:

--bibliography FILE => --metadata bibliography=FILE --filter pandoc-citeproc
--csl FILE          => --metadata csl=FILE
--citation-abbreviations FILE => --metadata csl-abbreviations=FILE
Change for latest pandoc-citeproc.
Changed --metadata to return Boolean True if no value.

Also documented in README.
Documented --bibliography, --csl, --citation-abbreviations.
Improved make_osx_package.sh.

New PackageMaker location.
New method of installing, to get pandoc-citeproc executables too.
Use embed_data_files.
Fixed make_osx_package.sh.
