Prevent name mangling of constructors, methods, fields and properties.

When applied to a type prevents all its members of being renamed.

It can be used to provide stable member names for access from handwritten ActionScript code or to provide .net stubs for ActionScript types when combined with NotConvertedAttribute:

	namespace flash.utils
	{
		using UnityEngine.Flash;
		
		[NotConverted]
		[NotRenamed]
		public class Dictionary
		{
			public object this[object key]
			{
				get { throw new System.NotSupportedException(); }
				set { throw new System.NotSupportedException(); }
			}
		}
	}
