Please, add a "weeks" setting in the Upcoming Events widget

Please, in the next version of Events+, make the queried weeks configurable.

Really, 5 weeks are too little and with each update I always have to change the code of Upcoming_Widget.class.php in order to get the weeks I need.

What's the problem of giving this option?
If this slows down the site, just warn the user, but give us this option.

Thanks.
