Trial and Free periods

Tier forms have been updated with the additional fields of Trial and Free tier periods. The trial period is trivial, the second one requires an explanation.

The Free period extends the very first paid subscription period to a specified number of days (up to 365). Tier upgrade to a tier with a free access period extends paid subscription period to a number of days as if subscriber joined the new tier originally on the very first date of their subscription.
