week view: don't limit the amount of thin "all day" event rows shown
I often have 4-6 "all day" events overlapping in my calendar. While it's fine to use the "X more events" trick in month view's cells when space is too constrained, this doesn't make sense in week view, because there is plenty of space. I shouldn't have to click and expand something (and the feature doesn't work in weekview, anyway) to see the 1 or 2 more events that weren't shown given how little space this requires in the "all day" header. Users won't have 30 all-day events, so I'm not sure we even need a limit there in the weekview.
