no net name for NC symbol

[ddrennan]

It would be nice if the netlister could avoid assigning a net name to no-connects. The advantage of this is that a NC would not have a net name when doing the board layout, which would avoid any confusion as to whether certain pins should be connected or not.

Unfortunately, this is impossible without a major change in the underlying way that netlists are computed, as it requires making the NC symbol a special case. This may well lead to subtle bugs, especially as the current NC symbol is -- and works like -- simply a completely normal symbol.
