Changes in this implementation

• Added new htmldomparser. A simple html parser implementation that assumes parsing is done in browser. Shold be compatible with john Resig's parser.
• Parser implementation provided support for ignoring tags that you do not want to convert.
• Parser also has an option to ignore dom elements with hidden styles.
• Added rules for parsing PRE, CODE, SPAN, DIV, TD, DL, DT
• Added support for ignoring tags that you do not want to convert.
• Improved "startBlock" method and renamed it to "block"
• Added support for nested lists
• Fixed some showdown rendering issues when a link has a nested image
• Some readability changes like collapse whitespace, treat images as block elements, do not output text if elements are empty.
• Added support for converting relative url's to absolute url's
• Dropped wordwrap function as it does not seem a good idea to introduce new lines in the converter. and wordwrap behaviro was not consistents as elements can be nested.
• Added support for refeence style images and links (option driven to choose between inline markdown formatting and refernce style formatting)
• Added ton's of unit tests.

Known conversion issues

If HTML tag is of following form. Then, currently showdown fails to render

    <a href="/some_link">
        <h1>
                <img src="/some_image_lin"/>
        </h1>
    </a>
