    Mirror Evolution calendar settings into our own schema
    
    Right now, we are hard-depending on the presence of Evolution by
    using its settings schemas. This is likely to be unpopular, and
    also causes instability if someone happens not to have Evolution
    installed, so install a schema that has the same data path as
    the Evolution schema, but a different name and install that
    for the keys we need.
    
    To avoid a string-freeze break, we rely on the translations in
    Evolution - if Evolution isn't installed, the key descriptions
    will be untranslated in dconf-editor.
