Added chainable route handlers for some routes.

Some paths can be specified in just one line.

Some tests are failing, so I'll clone your branch @SamuelPinho and have a look at what's wrong. I like the idea of making the code more concise with chainable route handlers!

Oh, I see what the issue is @SamuelPinho. We are currently running Express 3.x and we haven't yet migrated the code to use Expresx 4.x, so we cannot implement chainable routes at the moment. If you end up refactoring the project to use Express 4.x, that would be extremely helpful!

Perfect @Engineering-Robert thank you.
Actually I'm trying to organize routes in one folder file by file and then load them through express-load. After that I think the refactoring is going to be more easily done.

That's awesome! Thanks a lot @SamuelPinho. Looking forward to your next PR!

@SamuelPinho Have you already ported to the code to express-4 in your fork?
