Use available space better on small width

[tpetry]

When debugging a simple Array for example the available space gets used very efficiently:

But when displaying objects too much whitespace is used on the left to have left-aligned labels:

Wouldn't it be more space efficient to move the labels (Class Name, Attributes) on top of their values so the values are better visible for small window widths? I need to scroll all the time for seeing one or two level nested structures because 29% of the space is "lost" on my example screen.

@willemvb could you take a look at this?

I added a PR to improve on this, awaiting @AdrianMrn's stamp of approval!

Looks great! @tpetry this will be included in the next patch (will launch sometime this week):

Thanks for the suggestion, keep 'em coming!
