* Updated GeoIP database for country blocking security.
* Fixed bug in Wordfence Security where we called reverseLookup in wfUtils statically and it's a non-static method. Thanks Juliette.
* Removed characters that are invalid in an IP address or domain from the Whois facility to improve security.
* Prevent users from creating 1 character passwords to improve security. 
* Fixed issue that caused an invalid variable to be used in an error message and improved Wordfence Security temporary file implementation for get_ser/ser_ser functions. Thanks R.P.
* Fixed issue that caused IP to output as integer in status msg. Not security related but display issue.
