Property "display" vs. HtmlViewer object model

[BerndGabriel]

As property "display" can switch an inline element to a block element and vice versa, the HtmlViewer's object structure, which divides the elements into TSection a block of text incl. inlined images and other TBlocks is obsolete.

In a revised object structure there should be no hard coded "display" property in the element objects. All objects should be able to be rendered with "display=inline", "display=block", ...
