URL filter reloaded

The drupal core filter "Convert URLs into links" (filter_url) is converting strings with "@" into email addresses even if there is no domain suffix present. (eg: working@home). While those strings contain valid domain name (home is a fully valid domain name by standard) with the current usage of "@" character this might not be the desired effect. (this is the topic of the ticket 2016739 )

This module contains a copy of the core filter filter_url with afox patch on #2016739. This sandbox module is intended to be used until #2016739 is commited and back-ported in D7 and if users don't want to patch the core.
