Add statesUNLOAD, LOADING, LOAED, ERROR management support for ajax request.

1. UNLOAD before ajax request send
2. LOADING ajax request send
3. LOAED ajax request respond success
4. ERROR ajax request respond error

var fn = function() {
   var deferred = Q.defer();
    setTimeout(function() {
        deferred.resolve();
    }, 100);
    return deferred.promise;
 };
var smFn = sm(fn);

1. Just pass your promise function in , you get a state manager function smFn . Now smFn.state == 'UNLOAD'

2. After you request smFn() . Now smFn.state == 'LOADING'

3. If the request returns success. Then smFn.state == 'LOAD'

4. Or the request returns error. Then you get smFn.state == 'ERROR'

sm(promiseFn, msg): get the promiseFn's state manager
