Enforces secure auto-configuration and fetching from Exchange (#50)

This patch enforces `mailnews.auto_config.fetchFromISP.sslOnly` and resets `mailnews.auto_config.fetchFromExchange.enabled` to allow fetching from Exchange servers when auto-configuration is enabled.

It also resets two auto-configuration URL preferences as doing so prevented users from re-enabling this feature.
