Reward levels, and the first official reward (Patreon)

So I've finally gone ahead and implemented reward levels to help show my appreciation for your patronage. A lot of it is giving you the chance to get more and faster of the stuff you like.

For your first official reward, here's an early look at the epilogue to Upstairoids, a look at Lexi's not-so-happily-ever-after. It's a first draft, but should still be pretty clean.

Thanks for pledging! I've included a .txt and .doc version.
