improved ODF output

ODF Header Level,
LaTeX Header Level, and
XHTML Header Levelmetadata to allow different header levels for different output formats
In general, OpenDocument support should be useable. You’ll have to use an external tool to manage citations, but at least your citekeys will appear. I had good luck when using LibreOffice to convert the OpenDocument format to Microsoft Word or RTF. So if you need to use one of those formats, this is the way to do it. Keep in mind that these formats are somewhat limited (particularly RTF), and things won’t translate 100% accurately.
