doxwiki 0.7.9 Released

Fixed css so outlines possible; added OutlineCss; added "noanchornames" in-file control for better Word compatibility. Added CheckSpelling and ImportPdf pages and PMs. CheckSpelling requires aspell to be installed (use cygwin on Windows platforms). ImportPdf just copies PDFs to the pdf directory and creates links to them. New default DefaultCss with old one renamed to PlainCss (has Steve's patch in it -- Thanks Steve!).
