When listing icons provided by a module, if there is a png and svg
with the same name, only the svg will be listed.
If a node asks for a png icon which is not known, but there is a
corresponding svg, that will be used instead.
switch node was missing font ( fa-ellipsis-h )
other nodes that have been updated with property option have the icon.
rbe-node and range-node have the icon to the left of property
its time the switch-node joins its siblings in uniformity.
