Improve AlarmEst

This used to work before but is now excluded:

	Alarm> p -lang=Est "ärata mind viis"
	The sentence is not complete

and one should say this:

	Alarm> p -lang=Est "ärata mind kell viis" | l -lang=App | p -lang=App
	alarm_time (MkTime H05 M00)
	alarm_time_hour H05

which (unfortunately) makes AlarmApp ambiguous for "alarm 05 : 00".
