Users are able to name a new class "Platform" even though there is already a class by that name in the Engine.

Users are able to add a new class to a project named "Platform" even though there is already a class in the Engine with the same name. This causes builds in Visual Studio to fail. There is no warning or indication that the name the user is giving to their new class is already in use.

1. Create a new project using the First Person Blueprint template.
2. Add a code class to the project. Name the new class "Platform".
3. Build the project in Visual Studio.
4. The build fails because the Engine already has a class named Platform.
