fix 19132 19135 ane partial fix 12090. implement nsIKBStateContorl for gtk. call ResetInputState from mouse button press. force ime to commit in ResetInputState and send the uncommitted text by using composition start/end and text event. move unicode conversion for IME into nsGtkIMEHelper class. r=erik
