Fixes #5845 Implement tslint for core files **What is this?** Implements tslint for both next and next-server, but keeps standardjs/eslint for the .js files that are still there, we're gradually migrating to Typescript. **How does it work?** Before every commit (pre-commit) we execute the following `tslint` command: `tslint -c tslint.json 'packages/**/*.ts` **TSLint Rules** In order to avoid as much changes as possible I marked some rules as false. This way we can improve the linter but making sure this step will not break things. (see tslint.json) **Note** After merging this PR, you'll need to update your dependencies since it adds tslint to package.json
