Added Minium framework to end-to-end test section

[mariolameiras]

I've had another alternative to protractor in the end-to-end section.

Minium is a great tool to test and automate any web application, including angular apps.

Hello, @mariolameiras thanks for contributing to this project. Would you be willing to add a high-quality section on how to use Minium with Angular? Simply adding a link to a framework that doesn't mention Angular integration is not helpful to developers looking for practical examples.

Hi @daniellmb makes sense. I'll try to add some more information about Angular

Or even better, instead of linking to your company website, include the pattern for integrating Angular tests with Minium in the e2e.md file.

this repo is a great resource, but imo e2e/string testing can be safely de-scoped. #2

if touching e2e.md, would seem prudent to trash the scenario runner bits as its been deprecated for some time now (https://code.angularjs.org/1.5.0/docs/guide/e2e-testing#e2e-testing)
