power-ethernet-mib and various metrics

There is code that supports the graphing of the following metrics, but it is commented out in "discovery/sensors/power-ethernet-mib.inc.php"

pethPsePortInvalidSignatureCounter
pethPsePortPowerDeniedCounter
pethPsePortOverLoadCounter
pethPsePortShortCounter

These metrics would be really nice to have when troubleshooting PoE devices. Is it something you could add support for?

Thanks
