Duplicate class template instantiations via %template changes

Browse source 
Named duplicate class template instantiations now issue a warning and are ignored.
Duplicate empty class template instantiations are quietly ignored.

The test cases are fixed for this new behaviour.

This commit is a pre-requisite for the near future so that the Python
builtin wrappers can correctly use the SwigType_namestr function without
generating duplicate symbol names.
