Promise.delay should allow numeric values that are not strictly integers

[benjamingr]

For compatibility with setTimeout both in browsers and in Node and with other promises library like Q and the Deferred object in the jQuery library I propose:

    Promise.delay(someValue);

To work with numbers that are not integers the same way browsers, other libraries and node would.

This would require changing:

       if ((ms | 0) !== ms || ms < 0) {
            return apiRejection("expecting a positive integer");
        } 

To

       if (typeof ms !== "number") {
            return apiRejection("expecting a number");
        }

For maintaining type safety but making interop with code that does delay(100*Math.random()) for example easier.

👍 The same rules than the ones of setTimeout should probably apply

Apply the ToNumber() abstract operation to timeout, and let timeout be the result. [ECMA262]
If timeout is an Infinity value, a Not-a-Number (NaN) value, or negative, let timeout be zero.

+1 to @Canop. Parameter validation in ECMAScript is an antipattern; coercion is preferred.
