upgrade mongo driver to 3.0.3 to prepare for mongolab upgrades

[jasoncalabrese]

This will be a hotfix going directly to master

[jasoncalabrese]

Compiles, but haven't tested yet, going to see if travis like it

[rnpenguin]

FYI, the reason we never updated the mongo driver was because it was the culprit of all that mysterious data usage; not sure if it is the case with the latest but it was definitely opening more connections than needed and using 10x or more data

[jasoncalabrese]

Yeah, I remember that issue, hoping the newest version would work, but enough changed to break the tests. Think xdrip already upgraded to 3.0. We might also be able to use 2.13 (http://docs.mongodb.org/manual/release-notes/3.0-scram/#upgrade-drivers)

I'm new to this project so I don't really know about the architecture, but what's the reasoning behind interfacing directly with Mongo from the uploader? Not needing a separate server process?

[jasoncalabrese]

It was an old method from before the rest api, we're not going to continue with it

[jareware]

@jasoncalabrese sounds good! If I wanted to read up on where the project's headed, where should I go? :)

Most of the discussion is over at https://gitter.im/nightscout/public, the NS uploader isn't being activly worked on now, the dev version has support for MQTT and Share BLE, but there are still some glitches that need work. The xdrip uploader is more active right now, but doesn't have mqtt support yet.
