Set custom SNMP Destination Port number

[DStobie]

It would great if when adding an SNMP device into GeoSCADA if we could modify the destination port number to something other than the standard port of 161 so that we can contact a communication device such as a Trio radio which is using Port Forwarding to read SNMP from more than one device that supports SNMP that's connected on the other side of the radio.

Thanks Dean, we'll review this. We can see the use case.
