Subject: [proto] Refining the Proto concepts

In an experiment to reduce compile times, I'd like to try reducing the
number of template instantiations tied to the use of Proto.

To do this, one could start by defining his own expression types instead
of wrappers of proto::expr, which is something that is more-or-less
promoted by proto-11.

However, the proto_base_expr and proto_grammar typedefs still force
those instantiations.

Would it be possible to refine the concepts so as to avoid this?
