Title: Improve JDocument:

-Add JDocumentImage
-Allow content without a charset to be output (useful for binary data)
-Allow complete removal of the meta generator element.
-Fix the bug that meta elements with the attribute http-equiv weren't set corretly. This breaks API compatability on JDocument::SetMetadata().
-Add improved HTML5 support for templates. (Controlled by a template parameter)

I kinda need the first two fixes for Joomla 2.5. So if anything else slows down this merge please post a short note and I'll remove it from this pull (and open a different one for it)
