Skinned devices don't have their sizes divided by their css pixel ratio.

An example is: The Z10 would be sized to its device pixel dimensions by
by default, even if there was a css pixel ratio defined in its file.

This also caused devices with skins (and how they were
originally styled) to break, so all CSS for each skin was updated. Now,
they only use padding to set themselves.

Note: Renamed the method in resizer.js to something more appropriate,
since formatSkin really did not make sense for what it was doing.
