Werner Almesberger 1cd079ee82 great atusd -> atben renaming: changed remaining references in tools/
- Makefile.common (MACROS_ben_jlime, MACROS_ben_openwrt), lib/atrf.c
  (atrf_open): changed HAVE_USD to HAVE_BEN
- lib/atben.c: changed "uSD version" in title to "Ben 8:10 card version"
- lib/atrf.c, lib/atben.c: changed all occurrences of "atusd" to "atben"
