Now when subs parameter is empty or the YouTube IDs are not specified,
captions will not try to fetch non-existent file.

It turns out that there was wrong invocation of toBeCloseTo() function. Most likely a typo.
Updated the readme.

Because sometimes the tooltips generated by qTip get in the way, and the controls becomes
not responsive, it was decided to use standard title attributes for tips.

Also along the way, an error was discoevered in Jasmine tests. It was fixed, but that test is
failing so it was marked specifically to be skipped when all VideoAlpha tests run.

For some reason the "muted" icon was not showing. Styles have been corrected.Now on focus background color is also simplified for div
.volume control.

When a VideoAlpha is present on the page, if the user tries to tab through out the entire page, eventually he will land on the VideoAlpha controls. The tab index order has been set up so that all control receive focus eventually in the order from left to right. When a control receives focus, it is hilighted. The last tab focuses the captions dialog. When the captions dialog has focus, the Up and Down arrows can scroll it up and down.
