feat: Add finish timestamp for every browser

[theghostbel]

Being applied we can see in console time (HH:MM:SS) when run completed. This helps in situations when you work for a while over some file and then look into console and don't know if current results are the freshest? You throw a look on clocks and realise - hey! it's five minutes old! I've forgot to click "CTRL+S"

Firefox 34.0.0 (Windows 7): Executed 98 of 98 (2 FAILED) (8.926 secs / 8.867 secs) finished at 01:16:27

Thanks, can you please change the commit message following this git commit message convention.

[maksimr]

@theghostbel we can improve code little:

var finishDate = new Date();
var formatTime = function(date) { return time < 10 ? '0' + time : time};
msg += util.format(' finished at %s:%s:%s', formatTime(formatTime.getHours()), formatTime(finishDate.getMinutes()), formatTime(finishDate.getSeconds()));

[theghostbel]

agreed

[dignifiedquire]

@theghostbel could you fix the code formatting issues that came up on travis please?

[theghostbel]

@dignifiedquire fixed, thanks for pointing!

Now all that's missing is to squash it into on commit then it's good to go from my side.

[theghostbel]

Squashed commits into one. For those who is searching "how to" squash commits for github`s pull request into one I'd recommend this article. Worked like a charm after I switched to simple push mechanism for forced pushes:

$ git config --global push.default simple
$ git push -f

@dignifiedquire, how to be when one of builds failed? :( Looks like it was kinda test build env ("iojs-1")

[dignifiedquire]

@theghostbel I've retriggered it lets see with what it comes back

[dignifiedquire]

@theghostbel could you rebase onto the latest master please?

[dignifiedquire]

@theghostbel ping

[theghostbel]
