[evolution-patches] Patch for week_view keyboard navigation

[Kidd Wang <kidd wang sun com>]

Hi,

We find some problem about keyboard navigation. An all-day event can't 
be moved
from Tuesday to Monday in week view. That's because the original code 
calculates
the offset of a day in the week without respect to the time zone 
settings of the calendar.
Enclosed is a patch adopting a more straightforward way to calculate the 
offset.

Regards
Kidd
