Assertive-Chai Based Specs to test Bacon.js on IE8

[vikikamath]

Pull Request to demonstrate #426

Note: IE8 is not supported by Expect API of chai.js. To work around this limitation, I used assertive-chai npm module that exposes only Assert API of chai.js.

• The Assertive version of specs can be found under ie8 directory.
• The Assertive version was written using a helper module to convert Expect API to Assert API. I am unsure if I should've committed it.

Please feel free to use as required.

To Run:

• npm install && cd ie8 && ./browserify.sh - This will generate new bundle.js under browsertest directory, using Assertive*.coffee spec files under ie8 directory.
• Open IE8 browser and open page to <Protocol>://<Host>[:<Port>]/ie8/mocha.runner.html
• If the tests do not load, open the Debugger (F12)-> clear cache -> Start debugging -> Prompt for reload page -> Agree

To Simulate #426

Replace line forNow = schedule[currentTick].splice(0, schedule[currentTick].length) in AssertiveTickScheduler.coffee with forNow = schedule[currentTick].splice(0)

IE8 will timeout.
