Annual memberships added (Patreon)

By request of a Patreon, I've added the option to pay annually.

This option will save you 8% of the fee, resulting in 1 month for free! I'm not sure if you'll be able to edit your membership to annual if you wish to do so, or if you'd have to re-sub for it to apply, but I'm fairly sure the staff at Patreon made it simple to adjust.

In any case, I want you all to know I deeply appreciate each of you being a part of my Patreon in any way you are, in any tier.
