Cleanup string matchers

Removed nested `StdString` namespace and added Doxygen comments.
Also renamed some matchers to avoid colisions now that there are
less separate namespaces for matchers to go to. Since this is a
breaking release anyway, it shouldn't matter, and the factory
functions that the users should use remain the same anyway.
