[1.13] Class names that have an Interface prefix but changed to be a normal class

[ichttt]

There are a few classes that have an Interface prefix but aren't interfaces:
IGuiListEntry in GuiListExtended
IOptionHandler in EntityOptions
IRecipeHidden
IScoreCriteria

[Pokechu22]

I'd suggest IRecipeHidden be renamed to DynamicRecipe since that describes its purpose fairly well/matches the name of isDynamic (func_192399_d).

n.b. This was an interface in 17w47a (possibly earlier), but became an abstract class in 17w48a.

Issues regarding class and package names are now handled in the MCPConfig repository.
