1. Moved _plugins into themes/classic/_plugins

I think it's probably better to ship plugins with themes to make it
easier to update them.
2. Improved 'install' rake task and made nicer output

+# Sitemap.xml Generator is a Jekyll plugin that generates a sitemap.xml file by
+# traversing all of the available posts and pages.
+#
+# How To Use:
+#   1.) Copy source file into your _plugins folder within your Jekyll project.
+#   2.) Change MY_URL to reflect your domain name.
+#   3.) Change SITEMAP_FILE_NAME if you want your sitemap to be called something
+#       other than sitemap.xml.
+#   4.) Change the PAGES_INCLUDE_POSTS list to include any pages that are looping
+#       through your posts (e.g. "index.html", "archive.html", etc.). This will
+#       ensure that right after you make a new post, the last modified date will
+#       be updated to reflect the new post.
+#   5.) Run Jekyll: jekyll --server to re-generate your site.
+#   6.) A sitemap.xml should be included in your _site folder.
+#
+# Customizations:
+#   1.) If there are any files you don't want included in the sitemap, add them
+#       to the EXCLUDED_FILES list. The name should match the name of the source
+#       file.
+#   2.) If you want to include the optional changefreq and priority attributes,
+#       simply include custom variables in the YAML Front Matter of that file.
+#       The names of these custom variables are defined below in the
+#       CHANGE_FREQUENCY_CUSTOM_VARIABLE_NAME and PRIORITY_CUSTOM_VARIABLE_NAME
+#       constants.
+#
+# Notes:
+#   1.) The last modified date is determined by the latest from the following:
+#       system modified date of the page or post, system modified date of
+#       included layout, system modified date of included layout within that
+#       layout, ...
