    Strip json and html from error messages

    Error messages were being passed with either JSON or HTML formatting
    leading to an unpleasant user experience. This strips the JSON or HTML
    tags and presents the clean error message to the user.

    Rewrote the lispy function to be more pythonic, added test cases
    and cleaned up some pep8 violations.

    Removed commented out cruft from a previous version of this
    patch.

    Changed the HTML details from a set to a list in order to ensure
    the ordering of the exception details.

    Added code to eliminate the duplicate detail messages from the list
    and reordered the assertion string to match actual output.

    Refactored duplicate elimination code to be more readable and
    reliable.

    Some reworking of the duplication elimination loop to make it
    more readable.

    Removed unneeded conditional to filter out empty elements.
