Migrating from 0.7 to 0.8

Promise now has only an empty init.

If you used one of the convenience init (with value:, with error: or with value:error:), they now moved to Future.

// Before
let future = Promise(value: 10).future

// Now
let future = Future(10)

// Before
let future = Promise(error: MyError.SomeError).future

// Now
let future = Future(MyError.SomeError)

// Before
let future = Promise(value: someOptionalInt, error: MyError.InvalidConversion).future

// Now
let future = Future(value: someOptionalInt, error: MyError.InvalidConversion)
