Move the monolithic jpeg viewer into its own subdirectory and split it into three (for now - maybe it should be split further) files - jpeg.c (the main plugin/viewer parts), jpeg_decoder.c (the actual decoder) and. for colour targets only, yuv2rgb.c. The intention of this commit is as a first step towards abstracting this viewer into a reusable jpeg decoder and a multi-format image viewer.
