using scope.$evalAsync instead of scope.$applyAsync

[karianpour]

Actually I am not specialist on Angular, but as the scope.$applyAsync is not supported before Angular 1.3 I suggest to have a version which uses scope.$evalAsync instead, to let the legacy systems to be able to use this library. In case someone encountered this issue "scope.$applyAsync is not a function", find and replace all the scope.$applyAsync=>scope.$evalAsync.
