* No initial copied object changed (this was a serious bug to modify these
objects. Previous version modified references and other texts using a
broken algorithm).
* Only new pads are numbered (therefore renumbering is used only in footprint
editor)
* Remove not working feature in circular array: now only use number for
pads (other options using alphabetical letters are removed: did not work
correctly).
* A more clear option is used to choose if the pads are numbered from a chosen
value or from the first available value.
* Adding a warning message if a parameter is incorrect.
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
