Month view: entries for one day are not displayed in chronological order

[lemagnecharle]

Later appointments are displayed before earlier appointment in month view. The error always seems to occur when an entry has more than a "30 minutes" timeslot.

Steps to reproduce:

• Compile the demo and run jetty.
• Visit localhost:8080.
• You are presented with the week view.
• Add an entry by clicking on the 09:00 timeslot on one day.
• Use the same day but this time add an entry which uses two consecutive timeslots (e.g. 10:00am-11:00am).
• Switch to month view. The 10:00AM entry will be above the 9:00AM entry in the month view.

itemSortOrder solved the issue!

Found the method org.vaadin.addon.calendar.Calendar#setItemSortOrder, set itemSortOrder to org.vaadin.addon.calendar.client.CalendarState.ItemSortOrder#START_DATE_DESC and everything is sorted according to date now.
