Change NameValue Collection to serialize like a Dictionary<string,string>

[runxc1]

So I was just splunking some of the data in mongo for some of the errors and noticed that the name value collection is serialized as just an array of arrays which seems about impossible to query off of in Mongo. I see that a couple of the checkins are around serializing the serverVariables. I don't need to splunk the data that much but the form it is in makes analyzing the data in mongo very difficult.
