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.

Input widget takes one variable path, and displays current value in
optional "value" labeled sub-element.
Click on optional "edit" labeled element opens keypad to edit value.
Operation on current value is performed when click on sub-elements with
label starting with '=', '+' or '-' sign. Value after sign is used as
operand.
