Dropbox link extension (Patreon)

After some consideration, the folders for HD/PSD/alt content will have their Dropbox links last for 2 months instead of 1. This is to account for situations where I post a picture to the public that was available here the previous month via early access. I think it's kind of bait-and-switchy if someone subs to get alt/HD versions of that picture, and realizes it was actually shared here the previous month and is thus inaccessible. The change also helps with situations where someone just narrowly missed the end-of-the-month cutoff. 

Early access folders will still last 1 month, since its contents are not divided per-month.

I have gone back and updated the November links to be active again, and since it's Christmas and near the end of the month, they will last until January 7th.
