Better type descriptions for part aspects

[md5i]

Issue type:

• :heavy_plus_sign: Feature request

---

Short description:

Aspects that accept lists as their argument don't declare specifically what type must be contained in the list. This is especially noticeable when dealing with easily confused types, such as blocks, items, and item entities. It would be nice if instead of showing List, they would show something like List(Entity).

Sorry, didn't mean to close this. I accidentally hit close in a sub-window off of the "Features" page, which I had though was closing the pane, not the issue.
