Graduate contrib 'uuid' into core. 

This has the following nice benefits:

  * The 'Uuid' wrapper type is gone.
  * 'Uuid' implements 'UriDisplay', 'FromUriParam'.
  * The 'serialization' example merges in 'uuid'.

Resolves #1299.

//! UUID path/query parameter and form value parsing support.
//!
//! # Enabling
//!
//! This module is only available when the `uuid` feature is enabled. Enable it
//! in `Cargo.toml` as follows:
//!
//! ```toml
//! [dependencies.rocket]
//! version = "0.5.0-dev"
//! features = ["uuid"]
//! ```
//!
//! # Usage
//!
//! `Uuid` implements [`FromParam`] and [`FromFormField`] (i.e,
//! [`FromForm`](crate::form::FromForm)), allowing UUID values to be accepted
//! directly in paths, queries, and forms. You can use the `Uuid` type directly
//! as a target of a dynamic parameter:
//!
//! ```rust
//! # #[macro_use] extern crate rocket;
//! use rocket::serde::uuid::Uuid;
//!
//! #[get("/users/<id>")]
//! fn user(id: Uuid) -> String {
//! format!("We found: {}", id)
//! }
//! ```
//!
//! You can also use the `Uuid` as a form value, including in query strings:
//!
//! ```rust
//! # #[macro_use] extern crate rocket;
//! use rocket::serde::uuid::Uuid;
//!
//! #[get("/user?<id>")]
//! fn user(id: Uuid) -> String {
//! format!("User ID: {}", id)
//! }
//! ```
//!
//! Additionally, `Uuid` implements `UriDisplay<P>` for all `P`. As such, route
//! URIs including `Uuid`s can be generated in a type-safe manner:
//!
//! ```rust
//! # #[macro_use] extern crate rocket;
//! use rocket::serde::uuid::Uuid;
//! use rocket::response::Redirect;
//!
//! #[get("/user/<id>")]
//! fn user(id: Uuid) -> String {
//! format!("User ID: {}", id)
//! }
//!
//! #[get("/user?<id>")]
//! fn old_user_path(id: Uuid) -> Redirect {
//! # let _ = Redirect::to(uri!(user(&id)));
//! # let _ = Redirect::to(uri!(old_user_path(id)));
//! # let _ = Redirect::to(uri!(old_user_path(&id)));
//! Redirect::to(uri!(user(id)))
//! }
//! ```
//!
//! # Extra Features
//!
//! The [`uuid`](https://docs.rs/uuid/0.8) crate exposes extra `v{n}` features
//! for generating UUIDs which are not enabled by Rocket. To enable these
//! features, depend on `uuid` directly. The extra functionality can be accessed
//! via both `rocket::serde::uuid::Uuid` or the direct `uuid::Uuid`; the types
//! are one and the same.
//!
//! ```toml
//! [dependencies.uuid]
//! version = "0.8"
