RUNTIME: Variable forcing now uses limited list and buffer instead of systematical instance tree traversal and in-tree "fvalue" to keep track of forced value for pointed variables (external, located). Pointer swapping is performed when forcing externals and located, with backup being restored when forcing is reset. Retain still uses tree traversal.

    CustomHtml widget allows insertion of HTML code in a svg:foreignObject.
    Widget content is replaced by foreignObject. HTML code is obtained from
    "code" labeled text content. HTML insert position and size is given with
    "container" labeled element.
