Fix an issue with the Tier Waifu Lover and some permissions changes (Patreon)

Hi, guys! I fixed a problem accessing many posts that the Waifu Lover tier did not have access to. If there is any post with restriction in that tier send me a message!

I also restricted access to some posts so that they are only available only to Waifu Collector onwards. 

To give some privilege to the tier.
