Stringify filtering out null values

[jwarkentin]

A recent change seems to be filtering out null values from objects when encoding them. I use the request module for Node.js which depends on node-querystring and this change broke my application.

Calling stringify() on an object such as {var1: null, var2: null} returns an empty string when it should not.

The way the official Node.js 'querystring' module encodes it, and the way node-querystring has up until now is '?var1=&var2='. There has been a long discussion over at jQuery trying to determine how to encode null variables with $.param() and they also settled on '?var1=&var2='. For a long time jQuery has encoded it by setting '?var1=null&var2=null', but that behavior has changed in more recent versions. Either way, they do not throw away the variable.

I'm impartial, I'll alter it to do key=
