[Bug-gnu-radius] something is missing in docs

[KubaTyszko]

hi
.
i just discovered that documentations is missing one sql statement (that 
creates table authfail)

here is the missing sql:

CREATE TABLE authfail (
  user_name           char(32),
  count               int(32),
  time     datetime DEFAULT '0000-00-00 00:00:00' NOT NULL
);

please include it because it takes some time to "guess" the right table ;-)

regards.
