Adds support for reverting to the Rockbox default WPS. Note that the rockbox_default.wps is a placeholder file and is never actually loaded - selecting it just causes Rockbox to clear its memory of any installed custom WPS. This means that it works cross platform. Also, small fix to boxes.wps (curse vi) and wpsbuild.pl - support for pure text WPS files.
