message: Remove no_run annotation from doctests
diff: //!
  //! To get started, we need to create a client:
  //!
  -//! ```rust
  +//! ```
  //! let client = stripe::Client::new("sk_test_YOUR_STRIPE_SECRET");
  //! ```
  //!
  //! so you may frequently need to refer to the [official API docs](https://stripe.com/docs/api)
  //! to determine which fields are required for either request.
  //!
  -//! ```rust,no_run
  +//! ```
  //! /* Creating a Stripe Charge */
  //! # #[cfg(feature = "blocking")]
  //! # {
  -//! # let client = stripe::Client::new("sk_test_YOUR_STRIPE_SECRET");
  +//! # let client = stripe::Client::from_url("http://localhost:12111", "sk_test_123");
  //! let token = "tok_ID_FROM_CHECKOUT".parse().unwrap();
  //! let mut params = stripe::CreateCharge::new();
  //! // NOTE: Stripe represents currency in the lowest denominations (e.g. cents)
  //! # }
  //! ```
  //!
  -//! ```rust,no_run
  +//! ```
  //! /* Listing Stripe Charges */
  //! # #[cfg(feature = "blocking")]
  //! # {
  -//! # let client = stripe::Client::new("sk_test_YOUR_STRIPE_SECRET");
  +//! # let client = stripe::Client::from_url("http://localhost:12111", "sk_test_123");
  //! let params = stripe::ListCharges::new();
  //! let charges = stripe::Charge::list(&client, params).unwrap();
  //! println!("{:?}", charges); // => List { data: [Charge { id: "ch_12345", .. }] }
