Revise all XXINTRNL_TEMP_RETURN_PTRVEC

[GoogleCodeExporter]

The current igraph_cliques.cpp will result in segfault because
XXINTRNL_TEMP_RETURN_PTRVEC is improperly used.

Note that if you want to return a ReferenceVector of an internal igraph
type, you must use it like this:

igraph_vector_ptr_t res
...
return ReferenceVector<Cpp_Type>::adopt<C_Type>(res);

Please rewrite XXINTRNL_TEMP_RETURN_PTRVEC to use this instead.

(I've reverted those for cliques back to r85 to make igraph_cliques.cpp
works properly, please check the rest yourself.)
