Next set of bitmap strips for the iCatcher theme, this time it's the 'small monochrome' icons for the Archos and all the remote screens. There's a little exception to the rule here - there already was a 'hold-s.bmp' which now becane 'hold1-s.bmp' because it's a single icon, only used on the Archos screens and named the bitmap strip hold-s.bmp to make it consistent with the other versions. Also simplified the code for displaying the static background images.
