Added tests to demonstrate poor performance on Safari (also applies in Phantom.js)

[OliverM]

I added a sample html file and identical tests to the Om and reagent test files to show how the issue applies only when using Kioo with Reagent.

I commented out the reagent test as it causes Phantom.js to fall over rather than crash gracefully or quickly, which can be pretty annoying when continuously testing.

Thank you for this!
