made routes a list

[josephmancuso]

This PR changes all route methods to lists to best use the new boolean logic in the route provider. In addition there is also a new change of being able to add a specific method type to all methods in a route group:

RouteGroup([
    get(..),
    put(..),
    patch(..),
    post(..),
], add_methods=('OPTIONS',))

In addition to all the request methods it handles by default (GET, PUT etc) it will additionally accept the OPTIONS method as well
