icons/rfm is not an icontheme. Instead, these are the icons necessary
for rodent applications to run when *no* icontheme is present or when
an icon is not available in the currently selected icontheme. 

Any gtk selected icontheme will override these icons.

These icons are not placed in hicolor, because to do that would make
them subject to be over written by other applications.

The recommendation to place application icons in hicolor is a misleaded
recomendation, just as the recommendation to use stock items when
possible, or the recommendation to use the gdk mutex for thread
control instead of a single graphic thread.
