[ticket/9992] Adding a limit on login attempts per IP.

Browse Source 
A new table was created to save all failed login attempts with
corresponding information on username, ip and useragent. By default
the limit is 50 login attempts within 6 hours per IP. The limit is
relatively high to avoid big problems on sites behind a reverse
proxy that don't receive the forwarded-for value as REMOTE_ADDR but
see all users as coming from the same IP address. But if these
users run into problems a special forwarded-for option is available
to limit logins by forwarded-for value instead of ip.
