Finalize fixture tests

[Havunen]

In dev branch we now have fixture folder that contains tests for different bundle systems. These tests have been ported from React to test Inferno compatibility. I have finished tests for browserify

Code here: https://github.com/infernojs/inferno/tree/dev/fixtures/packaging/browserify

but all others are still in progress. Finalize other bundling tests and add rollup there.

Objective is to test inferno in different environments before making new release. It can be manual test for now, automation is plus.

I've ported the tests over correctly and validated they work. If we built a small demo app we could validate the render with karma. That's as far as I've got for automation.

Sounds good :)
