Seems there is a mistake between a copy constructor and the Copy method
which exists for some BOARD_ITEMS, but not all (because currently this
method is not needed in C++ Kicad code for track/vias)

The Copy method copy only some values from an existing source to an
existing target.

The default copy constructor creates a clone (a new item) of an item.
This is very different.

I'll add a Copy method (mainly for python scripts) for tracks/vias soon.

For now, to create a clone of a track/via using the default copy
constructor, try to use something like :
newtrack=oldtrack.__class__(oldtrack)

(I am hoping it works, I am not experienced in Python language)
