The sitemap currently includes CSS (*.css) files, as well as SASS (*.sass or *.scss) files (which end up being converted into .css files). This patch skips those files in the sitemap.
The sitemap.xml format contains an optional element "changefreq" which, if given, tells the search-engine robots approximately how often a given page will change. For example, the front page of a site might change daily, but archived blog posts probably never change. This branch checks to see whether a "changefreq" has been specified in a file's YAML front matter and, if so, this is added to the sitemap.xml. (If no changefreq is specified then the element is omitted from the XML.)
