[Title] Fix the incorrect behavior touch sound on single tap event.
[Issue#] DCM-1690
[Problem] There is no touch sound when tapped object that has JQuery mobile's vclick event.
[Cause] Link event check that node has Atag, button, input tag or onclick event only.
[Solution] Improve checking routine to decide sound effect on link event.
- Add '!rendererIsEditaple()' for loop conditions to ignore input-text or textarea tags.
- Use supportsFocus() instead of checking Atag, button, input tags to support vclick event.
- Add mouse down, up, over event to play touch sound.
- isRoot() moved because play touch sound when root node has Atags.
