lm32-vuart was destroying the tty it was run into. And ctrl-C was
not working (the initial message "press ctrl-A" was not really
visible).

This removes part of the cruft of the program. It also adds a little
delay when no bytes are there to read from FPGA to releaf a little
the load on the ARM CPU.

  - fix option parsing, and a comment about terse/quiet and verbose
  - added -o (range) and -g (reen). Documented -y (ellow).
  - renamed prgname to pgrname ("prg" like "prog"), as we have 86 of
    them and only 2 pgrname in wrs_version, which was a typo I fear.
