Arduino Proto Shield Rev3 incompatible with PoE

The pre-assembled Arduino Proto Shield Rev3 will not mount flawless on a Yun with PoE.

The PoE module is a bit too high and touches the bottom of the proto-shield-even without electronic components soldered on the proto-shield.

Keeping proper distance between the shield and Arduino results in a non-snug fit of these two. Making the legs on the proto-shield longer gives an issue with standard Arduino enclosures...

I think that's a common issue with PoE modules: they take space. Long stackable headers solve the issue
