[evolution-patches] fix for the bug #321088 [calendar]

[chen <pchenthill novell com>]

Hi,
  Have attached the fix for the bug. Reduced the canvas area so that the
effect movement in a wrong direction is not visible. Set the
scroll_increment to days width. Show only 35 days in the canvas since we
query free/busy only for those. Set the canvas view to meetings day
start instead of time.

thanks, Chenthill.
