Changed structure of Calendar-View. Filter-arguments are passed in the URL.
Needs work (but not broken):
  - Links to calendar
  - Buttons in day view
Bugs:
  - Date selector in filter fieldset.

Implemented JS pop-up for events. WIP.
Added a nice little fade-in animation and a 700 ms delay.
Big remake of the calendar system. Calendar, Day and List have each their own page now
(nicer URLs). Day has been changed to vertical view, but it still needs styling.
Started work on the new list, with sorting and limit options.
Removed two old files, that is not needed with the new calendar.
Further work on the calendar list, mostly styling.
 Missing feature: soring.
Did some more styling, added a button for event creation and added link for events in day view.
Bug fixes:
 - jQuery datepicker now works when no compare string is specified for DateTimeEditor
 - Events in day view are displayed correctly.
New 'bug':
 - Invisible events may be deselected in the filter, and thus removed.
Added sorting functionality and links to events and users in the list.
Commented functions in CalendarController and added some helper functions in EventFilter.
Fixed the filtering bug.
