Problem with UNO_R3 PCB footprint.

**BUG** Concise problem statement: When placed on PCB, UNO_R3 PCB footprint shows connections not made in schematic symbol. Steps to reproduce bug: Schematic and Schematic Design Manager for UNO_R3 symbol shows no pins connected. PCB and the PCB Design Manager for PCB footprint placed in PCB layout shows ratline connecting 5V **and** IOREF pins on P1! It also shows ratlines connecting AD4 to SDA and AD5 to SCL. This is not what the Schematic and the Schematic Design Manager shows!! Looking at the PCB footrint, it has been imported from Sparkfun. * The SDA and AD4 pins are assigned to a net called AD4SDA * The SCL and AD5 pins are assigned to a net called AD5SCL * The GND pins are assigned to a net called GND * The 5V and IOREF pins are assigned to a net called +5V It looks like these connections were either in the original Sparkfun footprint pin to net assignments or have somehow been introduced in the import process. * The problem must be fixed by removing the pin to net assignments leaving connections so that they must be made in the schematic and not implicitly in the symbol. That way, only what is drawn on the schematic defines the connectivity and that is also then exactly what is shown in the PCB.

Any Fixed version?

I've cloned the original, fixed it and saved it in `My Parts` as `UNO_R3`. * Can you delete the system `UNO-R3` and replace it with mine? Then I can delete my `UNO_R3` from `My Parts` and users will see the same part but with the net names fixed.

The UNO_R3 PCB footprint in the EasyEDA library is now fixed. (and my own copy has been deleted.)
