Subject: [PATCH] Get email forwarding working.

* enable smtp
* forward mail to the enclosing system's SMTP server
* correct errors in the GF_SERVER_ROOT_URL and GF_SERVER_DOMAIN setting, which messed up links in sign-up messages (and probably in password-recovery emails as well)
* add ability to override logging settings from TTN_DASHBOARD_GRAFANA_LOG_MODE and ..._LOG_LEVEL variables
