request support for image maps

[ec1oud]

I'm sure you consider this rather old-school, and I've hardly ever used them myself. But for the sake of light weight, in a browser that does not have a JS engine, it can be useful to make areas of an image clickable in this way. (Ulterior motive: I'm investigating whether we could consider making use of them in Qt documentation occasionally, and Qt Creator currently uses litehtml for its help engine) Surprisingly this feature is still part of HTML 5. https://www.w3docs.com/learn-html/html-map-tag.html

See http://ecloud.org/misc/qt/controls-doc-proto/ : the first tab has an imagemap

OK, agreed. I'll add support for image maps.
