add colored tiles to animate during Simon's turn

also start Round #1 once page is loaded
implement replaying color/sound sequence

Mocha + PhantomJS don't seem to generate 'animationend' events, therefore
making it difficult to test the progression of the sequence replay

if I was to use setTimeout() of 1s in place of 'animationend' event, I could
leverage SinonJS's useFakeTimer to advance the clock 1s forward to trigger
the timeout and verify replaySequence() is called at each step with an
increasing index
