Added some aliases:

- `b' is now an official alias for `break'.  It used to be an unofficial
  alias, but this was broken by adding the `bt' alias for `trace'.
- `t' is now an official alias for `trace'.  It used to be an unofficial
  alias, but this was broken by adding the `thread' command.
- `registers' is now an alias for `show registers'.  This is a hack to
  break the unofficial `r' alias for `reset'.  `r' really means
  `registers' in some debuggers, so I sometimes type it accidentally and
  am annoyed when it resets the system.  A short command shouldn't have
  such a large effect.  Now at least `res' must be typed to disambiguate
  `reset'.
