Title: Some usability enhancements

1. Added package nickname :gflags.
2. Added allegro support to (command-line)
3. Made define-flag return the flag symbol (mimicking defparameter)
4. Made register-flag delete obsolete flags (for 5. below).
5. Added generate-usage-string function which uses the flag names and
help strings.

With a little more work this library will be better than other getopt libraries. Nice. :-)
