Bugfix:

Certain events were not correctly displayed, namely those with
"starting minutes" larger than "ending minutes" (for example an event
starting at 07.30 and ending at 18.00) was displayed as ending at 18.30.

Also added more informative text for events in the weekview.
Events starting and ending on the same day is mentioned with start
and end time.
Events that span across multiple days is also mentioned with start
and end dates.
