Allow field access in queries

[EricBourland]

Would it be possible to support the following syntax instead of using getters?

JinqStream<Product> query = streams.streamAll(session, Product.class)
     .where(p -> p.ProductId == 15);

Also, #14

It's doable, but I can't justify putting in the time needed to implement it at the moment.

I don't think I'll ever get around to making this change, but I think it's still good to have the issue around.
