Support balloon on touchend

[miteshjmitr]

Is your feature request related to a problem? Please describe.
The problem is when a user selects a text in bubble mode there is no event attached when the touch ends and the user cannot annotate the selected text.

Describe the solution you'd like
If we could add the event listener for touch end in _addEvent function eventWysiwyg.addEventListener('touchend', event.onKeyUp_wysiwyg, false); In code view area auto line context.element.code.addEventListener('touchend', event._codeViewAutoHeight, false); and in _removeEvent add eventWysiwyg.removeEventListener('touchend', event.onKeyUp_wysiwyg);

Describe alternatives you've considered
If this does not help if we could add support for touch events so that it can support mobile devices?
