[evolution] GalViewCollection: Add a "system-directory" property.

[Matthew Barnes <mbarnes src gnome org>]

commit 695e0dba7040a9693d4f08b404753ae910d9182b
Author: Matthew Barnes <mbarnes redhat com>

    GalViewCollection: Add a "system-directory" property.
    
    Just readable for now, but I plan to make it also construct-only.
    
    New functions:
    
      gal_view_collection_get_system_directory()
