Title: Proper std::ref semantics

This pull request ensures proper `std::ref` semantics and makes `get` and `set` on `table` obey those semantics.

A `sol::ref` type was added to make the `lua.get>` less painful than `lua.get>` syntax, and `sol::ref` is just a using alias for `std::reference_wrapper`.
