v0.1.0

Added

• Html2Text class that converts HTML to formatted plain text.
• DomDocumentFactory to get a DOMDocument from a string.
• The concept of node converters: if you want to change how a certain element is converted to text, you can build a custom node converter for that element and add it to the Html2Text class (Html2Text::addConverter()). This will also replace an existing converter for that element type. You can also just remove an existing node converter without providing a new one, by calling Html2Text::removeConverter().
• Functionality to control which elements are skipped (Html2Text::skipElement(), Html2Text::dontSkipElement()).
