Bug Fixes: * Fixed and issue that suppressed exceptions in PDF builds. Features: * Allow a source to be included as a section so large documents can be broken up. * Added section link support to Markdown output. * Added list support to PDF output. * Added include option to explicitly build sources (complements the exclude option though both cannot be used in the same invocation). * Added keyword-add option to add keywords without overriding the default keyword. * Added debug option to doc.pl to easily add the debug keyword to documentation builds. * Added pre option to doc.pl to easily add the pre keyword to documentation builds. Refactoring: * Improvements to markdown rendering. * Remove code dependency on project variable, instead use title param.
