There is nothing PCB-frame-specific about this function,
it is equally applicable to an frame, for example
PCB_EDIT_FRAME and CVPCB_MAINFRAME, which have EDA_BASE_FRAME
as the nearest common ancestor, except KIWAY_PLAYER,
which is not really concerned with this kind of UI event method.
Text arrays can now use "%s" as a placeholder to be substituted with the array index.
Also expand menu options for move exact, arrays and duplicate.
Minor fixes for arrays - use proper unit parsing, add numbering start for circular arrays
Add circle radius indicator to array dialogue
