Added ability to add additional graphs based on Zabbix Tags added to the Trigger or the Host.
Added PHP error logging (informational / warning) to the debug logging.
Added ability to login to the mail server (username/password).
This release also includes enhancements and bugfixes after the v1.26 refactoring that was required.
Note that some output vars for Twig have changed! Please refer to the wiki for more details (major difference is using ARRAYs in Twig instead of numbered vars).
