ADDED: New ERC test for mis-match GND pins 

If you have a pin with a label containing the letters "GND" in it and it
is not connected to a net with a label also containing "GND" AND there
is another pin on your symbol that _is_ connected to a net containing
"GND", then there is a likelihood that you have accidentally mixed up
your connections to the GND pin
