Review deployment script

I recently added [a deployment script](https://github.com/bluzi/name-db/blob/master/deploy/deploy.collection.js) and [Travis deployment](https://github.com/bluzi/name-db/blob/master/.travis.yml)

I'd love if someone review it and write in this issue if there are things that could be better implemented.

Thanks!

*Some info about what this script actually does:*
Every time a branch/pull request is being merged to the master branch, Travis execute the deployment script at`deploy/deploy.collections.js`.
This script connects to a MySQL database, checks to see what changed in `collection/`, and updates the database. (removes/changes/adds data, so it'll be exactly like `collection/`)

The MySQL database from above, is being used by [the API](http://54.161.117.62/david) to deliver the data. ([see code](https://github.com/bluzi/name-db/tree/master/api))

Read deploy/deploy.collection.js, the similarly referenced deploy/deploy.collections.js, and .travis.yml first. Trace how the deployment script processes collection/ and synchronizes MySQL, then compare its assumptions with api/. Done means documenting actionable findings in the issue and identifying any agreed improvements.
