Change some defaults with MongoDB and stderr

* Set some DB options to their assumed defaults from http://mongodb.github.io/node-mongodb-native/2.0/api/Server.html ... relates to https://github.com/christkv/mongodb-core/issues/66#issuecomment-165052045
* Set some replset defaults to their assumed defaults from http://mongodb.github.io/node-mongodb-native/2.0/api/ReplSet.html ... relates to Automattic/mongoose#3588 (comment)
* Move/change a stderr message to debug mode of *node*... clear up the logs a bit since script source may not be found just yet. This only happens on pro so far and probably deals with streams not ready yet. Applies to OpenUserJS#430
* Move S3 source not found stderr to debug mode of *node*... known issue of OpenUserJS#486. Applies to OpenUserJS#430

**NOTES**
* This will be a test whereas unless it's a huge bug I can't take pro down for at least 3 days, give or take to see if this helps or hinders from OpenUserJS#845 backout.
