Added more enhancements to upcoming notifications.
1. Modified notifications core to have a new template type of "Autoship" (This may be relabeled to a different name depending on system preferences) These Templates are for use with Autoship notifications, which are managed from the Upcoming Notifications screen. Templates of this type support alias' specific to autoships, and related shipment & payment profile details.
2. Added CCFirst6 and CCLast4 columns to the payment profile table. Added payment profile history as a standard table (this may already exists in some installed instances). History table now also tracks CCFirst6 and Last4
3. Added simpler to use Auto-send notifications capability to Upcoming Notifications screen. Any configured upcoming notification events that are set to "Auto Send" will automatically prepare and send emails. This shortcut eliminates the need to use the Automated Notifications screen to automate this process.
4. Added "delivery window" for upcoming notifications. The process runs regularly, but the emails will only be sent during the specified time window. Any notifications that occur outside that window will be sent at the beginning of the next valid time window.
