Fixed out of memory error that arose due to generation of too many
channel guide views. Also, make ChannelGuide come up by default now.
If this slows you down too much, edit ChannelGuideView.java and change
the implementation of endTime() to return an earlier time (change the
3L to however many hours you want):
	Date result = new Date();
	result.setTime(beginTime().getTime() + 3L * 60L * 60L * 1000L);
