Minor change to $5 tier (Patreon)

So since we're using discord more often than not now, I've decided to move down the 'get access to WIP stills' bonus to $2. This way, everyone gets access to WIP stills now. I won't feel bad if every $5 dude demotes to $2. Lol. It's just easier this way. Anyway will post a work in progress still of my short animation in a bit. :)
