@jenweber As per our discussion this PR represents the first step to adding more tests and linting.
In this PR:

• Upgraded all packages to latest versions (since there are mostly linting packages nothing should break)
• Added repository property to package.json
• Set up for markdown linting using popular tool remark.js
• Added mark down linting presets (this is up for discussion I just though this would be most appropriate once)
• Started setting up travis to run tests and linting (it is expected for build to break as I have not updated all files according to new linting rules I will do so we confirm presets)
• Added editorconfig with some common configurations (this is also up for discussion)

Let me know what you thing about this changes.

I love it! Merged. Thank you so much.

Good news! Travis config works like a charm and there are only a few linting things that need to be fixed (missing images). CI is now in place for PRs moving forward.
