[Evolution] Evo 0.11 Calendar View->Week display bug

[Terry Browning <terry conflux nihil demon co uk>]

Running Evo 0.11 under Mandrake 7.0:

The View-Week (not Work Week) display of the Calendar has a bug.

I've tested it with a variety of StartOfWeek days, and the result is the
same.

All appointments on the LastDayOfWeek are displayed as if they begin on
the previous day and cross midnight.

For example: If I start the week on Monday, then Sunday's appointments
are displayed as if they start late on Saturday and overlap Midnight.

This looks like an off-by-one error when taking the start date/time of
the appointment, moving it a day early, but honouring the correct day
for the end of the appointment.
