Rox port nuvoX 0.4 Icon Theme

NOTE: This is a version of nuvoX theme that has been re-packaged for Rox-Filer.
In most cases this just involved renaming files to match the standard mime-type names. In some cases I added new icons.
---------------------------

Just unpack the iconset to ~/.icons or /usr/share/icons

note: "~" means is your home directory, i.e.: /home/<YOU>/.icons
