Fix crash when creating an array of footprint fields in board editor. 

Attempting to create an array of footprint child objects other than a pad
causes the crash due to the fact that only pads where checked.  The change
now checks if any object has a footprint as a parent.  This should prevent
any future issues when new footprint child objects are added.

There was also another subtle bug fixed when more than one child object of
a footprint were selected, the array feature would make as many copies of
the footprint as selected child items.
