Title: JS error in domadapter.keys method in IE versions below 9 

Array map method is supported only from IE 9 and hence in versions lesser than that usage of map method is throwing a javascript error. In this case in domadapter.keys method. Fixed it by checking for the support of the method and creating the keys array manually if map method is not supported.
