UCLASS_HideCategories syntax is not consistent with UPROPERTY_Category syntax

When the Category specifier of a UPROPERTY has more than one word, using the UCLASS specifier HideCategories requires the category name to be written all as one word even if the UPROPERTY is separated by spaces.

Ex:
Both (Category = "New Random Category") and (Category = "NewRandomCategory") would require UCLASS(HideCategories = ("NewRandomCategory"))

This could be confusing since the syntax of the categories does not match.

1. Open UE4Editor (any project)
2. Add code to project based on Actor (MyActor)
3. Add the following to MyActor.h
   • Add to UCLASS macro

     HideCategories = ("New Random Category") 
     

   • Add to class declaration

     UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "New Random Category")
     	bool Choice;
     

4. Compile
5. Create and open blueprint based on MyActor

Result:
Choice variable is visible in the editor even though the Category and HideCategories names match.

Expected:
Properties are hidden when HideCategories string matches Category name string

hideCategories = (ActorTick) won't work in 4.12
