Check status of PR

[cconcolato]

We need to add a TravisCI script that checks when someone makes a PR to make sure that the PR cannot be merged if one of the following criteria applies:

• it's touching the JS or HTML
• it's removing something from a CSV
• there's already an entry with that value in the CSV

The TravisCI integration is easy. The writing of the checks needs work.

Except that we have an example here where they are deliberately updating/clarifying an existing prior entry that they registered...

I hadn't noticed. At least, the fact that the merge is not possible would raise the question. We probably can merge by overriding the script result.

We handle manually for now
