Calendar: Option to start Month View with current week
Currently the Month View defaults to always start with the first week of a month. Like this, one can see all the weeks of a particular month.
Some people are more interested in seeing upcoming events/weeks rather than passed events/weeks. There should be an option to let the Month View start with the current week. Showing the weeks to come, up to a range of one month. This would be equivalent to scrolling down to the current week when opening the Month View while month-scroll-by-week is enabled.
- adds an option in Edit->Preferences->Calendar and Tasks->Display
- the option is disabled by default
- enables above behavior in e-cal-shell-content.c
- since List View gets its date range the same way as Month View, this also changes the behavior of List View to show respective ranges.
