Fakes - no way to override promise library in fakes

[fearphage]

Fakes are hard coded to use the global Promise library:

sinon/lib/sinon/fake.js

Lines 64 to 78 in 9d4a01b

	fake.resolves = function resolves(value) {
	function f() {
	return Promise.resolve(value);
	}
	return wrapFunc(f);
	};
	fake.rejects = function rejects(value) {
	function f() {
	return Promise.reject(getError(value));
	}
	return wrapFunc(f);
	};

There is no way to override this behavior and use an alternative library (like bluebird).

Similar interfaces that support this functionality:

• sandbox.usingPromise()
• stub.usingPromise()

This has been fixed with #2301
