Layout Mixin does not correctly vertically align

[rsaccon]

see http://jsfiddle.net/rsaccon/kbKsW/2/

documentation/example at packages/sproutcore-ui/lib/mixins/layout_support.js is also wrong

Also it is not clear to me whether the Containerview should have the Layout-Mixin, if yes, it results in a Runtime error, if not, the wrong vertical alignment as described above happen.

Looks like the issue is that jquery isn't appending "px" to the styles. will investigate.
