Usage

`javascript
var deferreds = [ $q.defer(), $q.defer() ]
var asyncVals = deferreds.map(function(deferred) {
return deferred.promise
})
asyncVals.push(3)

$q.allSettled(asyncVals).then(function(values) {
expect(values).toEqual([
{ state: 'fulfilled', value: 1 },
{ state: 'rejected', reason: 2 },
{ state: 'fulfilled', value: 3 },
])
})

deferreds[0].resolve(1)
deferreds[1].reject(2)
`

Also works with objects:

`javascript
var deferreds = [ $q.defer(), $q.defer() ]
var promisesArray = deferreds.map(function(deferred) {
return deferred.promise
})
var promises = { a: promisesArray[0], b: promisesArray[1], c: 3 }

$q.allSettled(promises).then(function(values) {
expect(values).toEqual({
a: { state: 'fulfilled', value: 1 },
b: { state: 'rejected', reason: 2 },
c: { state: 'fulfilled', value: 3 },
})
})

deferreds[0].resolve(1)
deferreds[1].reject(2)
`

Also provides
* $q.map: works like Bluebird.map or Bluebird.props depending on whether an array or an object is passed.
* $q.mapSettled: Works like $q.map but with the settled semantics.
* $q.resolve: Works like Bluebird.resolve`.
