Not currently using Mongo

[avanderhoorn]

Not sure if people know, but things are currently configured not to use mongo, its currently using the mock data source. For this to change, see the following:

• https://github.com/Glimpse/StickerApp/blob/master/server/config.js#L6 This config needs to be updated to say mongodb which will point to https://github.com/Glimpse/StickerApp/blob/master/server/db/sources/mongodb.js

This might have been designed to be this way, but I thought that I would mention this just incase people assumed it was using Mongo. This switch was put in to make it easier for novice users to get up and running.

This PR, #27, adds the Mongo DB Settings - I believe that Charles will pull this in with his changes when he switches the client to use the new sticker microservice that includes the mongo db support.

Note that this won't be checked into master until after Build.

This was addressed with #35.
