Autocomplete - Updated the setItemValues() method to support fireEvents as parameter.

ComboBox - Fixed the inconsitent triggering of change event (Solution : make use of internal select2js event).
TimePicker - Update the recent changes on setValue() overrides.
GMD Addins - Added missing GMD Resources.
Provided tests (setValue(value, fireEvents).
	- AutocompleteTest, ComboBoxTest, TimePickerTest.
