Updated not to add "friend class" to embedded private list so it can be accessed. (#1625)

Browse Source 
* Updated not to add "friend class" to embedded private list so it can be accessed.

* Added a list to hold all friends class decl so able to specifically make sure not to remove them from io source but not to allow is source for others.

* Added namespaces to class names for comparison as class name only needs to be unique within the same namespace.

* Added if NULL check before getting friend decl type string.
