kdepimlibs: @since 4.11 in KDE/4.10 branch

[Albert Astals Cid]

kdepimlibs KDE/4.10 branch contains this

./akonadi/itemfetchscope.h:237:     * @since 4.11
./akonadi/itemfetchscope.h:245:     * @since 4.11
./akonadi/calendar/incidencechanger.h:76: * @since 4.11
./akonadi/calendar/fetchjobcalendar.h:43:* @since 4.11
./akonadi/calendar/history.h:53:   @since 4.11
./akonadi/calendar/calendarbase.h:47:* @since 4.11


What's the proper fix? Removing the methods or changing the @since to the 
proper introduction values?

Cheers,
  Albert
