updated this test to test the new cr_declaration_to_string () api.

* tests/test4-main.c: updated this test to test the
new cr_declaration_to_string () api.

* src/parser/cr-declaration.[ch] (cr_declaration_to_string ()):
Added this new api to allow the serialisation of css declarations.
This is not well tested yet, but it works.
