VFile: added new formats 'jpeg' and 'jpeggrey'. Decompression is done

Browse source 
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.
