Issue #53: Refactor TemplateFilterDecorator

 - Add ability to define a wrapper element through the "decorator" attribute. If no wrapper element is defined <div> will be used as default.
 - To wrap the content either a wrapping element needs to be defined or additional attribites need to be defined on the <ktml:content> tag
 - Default attributes can be set through the constructor and will be merged with the specific attributes defined in the tag
