Ignore Eslint errors in src/**/node_modules (allows package development inside /src without breaking ESLint and babel-loader)

Created by: alex-pex

Exclude node_modules from source compilation (babel + advanced feature).

This is a small change which allows package development without the whole lerna + babel toolkit : It's workspace package INSIDE src folder. Apart from the lint issue, everything else is working out-of-the-box!
