Adding more information about failed tests

[marciovicente]

As developer running wraith in continuos integration environment, I need more information about which tests have failed. So, I change a little bit the code to generated this log in console.

I know this code increase the complexity of code, but I think it's very important.

Look the screenshot:

@ChrisBAshton could you take a look here? 😁

Hi @marciovicente, neat idea! What's the most useful feedback we can give to the developer? I think something like this:

Failures detected:
    buttons failed at a resolution of 320 (4.14% diff)
    buttons failed at a resolution of 624x768 (30% diff)

Steps:

1. Add ':' to end of 'Failures detected'
2. Add a few spaces before listing out the failed item
3. This also needs to support cases where the height has been set manually (see the second failure in my example above)
4. Put the % diff in brackets after the message
5. The red color is nice but I think \e[31m is Unix-only. We have to try to support Linux, OSX and Windows, so I'd be inclined to remove it.

Do you think you could tweak your PR to do this? That would be great!

Look this commit also. It's a smooth change, instead parse a string like 320x480_phantomjs to integer (returns 320), parse string by underscore and get first parameter (the resolution / returns 320x480). I think it's a better approach, once now you can pass height to screen_widths.
