gEDA: Default pinnumber for net attribute?

[Wojciech Kazubski <wk@ire.pw.edu.pl>]

Hello!
As now all net= attributes must contain a pinnumber(s) after a semicolon, like
net=VCC:14
in the case of power connection it looks like 
net=VCC:1
This is no problem if the power symbol is not editable, since the attribute is 
made invisible and a separate text VCC is displayed.
But if I try to make the power symbol editable by making the value of the net= 
attribute visible, a pinnumber also appears so the power is now labelled 
VCC:1
this looks strange for some people, who are not familiar with gaf. It would be 
better to have only VCC visible as a power label.
The appended patch makes 1 a default value of pinnumber in net, do
net=VCC
is equal to
net=VCC:1
There is one drawback, this patch removes an error message and a broken 
netlist may be created without warning. It should be good to limit this 
default to devices with only one pin, but I dont know how to make this.
