querystring.stringify creates different results depending on object property order

[SimplGy]

> qs = require('querystring')
> qs.stringify({foo:'foo',bar:'bar'})
'foo=foo&bar=bar'
> qs.stringify({bar:'bar',foo:'foo'})
'bar=bar&foo=foo'

Even though all modern JS interpreters iterate object properties in the order that they are defined, this is not to be counted on from the spec, which says object property order is not guaranteed.

Maybe (probably) non-deterministic query string output is acceptable to most people since the query string spec doesn't care about order. If you are using this for something else though, maybe you care about the param order. I need to for my use case.

Alphabetizing before stringifying is an easy solution.

Seems like a candidate to go into core, but I understand if it's not seen as needed.
