 * Raise requirements and modernize some conditionals
 * Refactor the meta description [ default ! ] extract_description "tagging" to better match text content,
     which now allows to use some standard matching p class selectors; Which are
        <p class="content"> or "excerpt" | "initial" | "meta" class selector names.
     So the length, placement and exact content of your SEO meta description excerpt default fallback extraction is in your hand.
     The previous method to extract by certain position of existing <p> tags was rather unreliable
     and produced some strange results.
     The workflow is:
        - If no meta description is set by you in the blog entry form,
        - this extraction check is run on the given body text keeping word boundary character and Unicode ranges and if there are no matches found,
        -the plugin config option set default meta description is used.
     The latter will also be used if the /permalink/ Custom Permalink (plugin) pattern is used for the entry.
