feature: implement recorder class to allow to record bookmark and repeat an interaction!

For example it's now possible to do something like this (could be easy to convert it to a auth brute force script ^^)

(new Stimuli)
	.recorder.start('foo_login')
	.browser.navigateTo('someUrl')
        .keyboard
		.typeText('#login', 'foo')
		.typeText('#password', 'something')
		.enter()
	.recorder
		.stop('foo_login')
		.replay('foo_login', 10);
