* Changed the lookup order for the logpath environment variable.  With the old order it would break CYGWIN when trying to use the windows USERPROFILE.  By using a HOME check first it removes an issue in Cygwin.
* Changed the markdown processor from markdown2 to Markdown so that table extensions could be added to the markdown syntax
* Added Mac OS .DS_Store files to the ignore list
