Issue 2501 upgrade 0.0.8

Currently, the `dev` branch creates and uses `client.json` which is actually a JavaScript file, not a proper JSON file.

This is fixed in i18n-abide 0.0.8.

There are a couple tweaks to tests, file names, etc so that the code works with an actual JavaScript file on the client side as well as proper JSON files on the server side for localization.
