A bunch of output beautifications and improvements, as well as doc fixes

 - Update manpage, we now report supported boards via -L.
 
 - Add some missing escaping for '-' characters in the manpage.

Corresponding to flashrom svn r543.

 - Shorten some of the really long device names, so that -L output looks
   nicer.
   
 - Display a "table header" for all entries/columns in -L output.
 
 - Make -L output tabular for all lists for better readability.
 
 - Do not print "unknown XXXX SPI chip" entries in -L output.
 
 - And random other cosmetics...
