Subject: [PATCH] LibGUI: Add Calendar property for mode

If a user selects Year as the default view mode for Calendar app, then
all apps using Calendar widget will default to this view if not
manually overridden with a Calendar::toggle_mode call.

This commit introduces a "mode" property that allows the selection of
the default mode for the calendar widget in GML files. In this way
there is no need to manually call toggle_mode when constructing
UIs with Calendar widget.
