[[ bugfix-20121 ]] Icon Picker: Use a popup stack for icon property

Adds a Property Inspector editor stack svgiconfiter which allows
the user to filter the icons by name. The stack can be closed
without making a selection by using the Escape key.

The svgicon editor now pops up the stack instead of the iconpicker
widget.
