Zeroshell 2.0.RC3

With the release 2.0.RC3 of Zeroshell some security issues have been corrected. Specifically, now the DNS works as cache and accepts recursive queries only for local networks if not configured otherwise. Recently, the DNS fully opened are being used to carry out DDoS attacks resulting in bandwidth consumption. For this reason, the migration to 2.0.RC3 is strongly recommended.
No-IP has been added as a provider for dynamic DNS and the recognition of 3G USB modems has been enhanced. You can now disable the virus scan of web pages resulting in improved performance of the transparent proxy on modest hardware.
Several fixes have been applied on the procedure for Backup and Restore of the profiles.
