VFile: added new formats 'jpeg' and 'jpeggrey'. Decompression is done
using module 'jpeg' by the Displayer class. (Unfortunately it's too
slow for real time.) Print file size in printinfo() method.
Vinfo: added -t option (terse -- one line per file) and usage message.
Vtime: use BasicV{in,out}File classes -- the minimum needed.
Vmkjpeg, Vunjpeg: new utilities for jpeg (de)compression.
