Title: Promise sequence fixes

Reported as issue #202:
On 2.0-RC3 Promise.sequence always returns Seq not the input datastructure.
This becomes an issue if you want to continue using the original datastructure like this:
val vectorOfPromises : Promise[Vector[_]] = Promise.sequence(Vector(promises)) //does not compile
