Tooltips for requirement items

[Madis0]

When hovering on a requirement item, perhaps this mod could show a tooltip like WAILA/HWYLA/WTHIT that includes:

• the icon of the item (if exists)
• the full name
• the category like "Entity Objective", "Item Objective", "Custom Objective"
• the minecraft: name (if F3+H is enabled)

That could fix the limited space problem, better illustrate the item with an icon and better describe what the user is reading at all with the category.
