Support for multiple purchases

[ghost]

Currently, when unlocking content for new points, you'll get access to all sold content on that thread, meaning that if there's one item for sale, which costs 1000 newpoints, and then in the same post a second item, that costs 10 new points, unlocking either one of them will unlock the other as well.

I don't know if this can be added/fixed

[clickbait]

while this is possible, i'll need to rewrite a portion of the plugin to make it possible.

i have an idea as to how i'll do it, but it'll likely break any previous purchases.
