We have box-models in CSS. They define how the dimensions of
elements are calculated. Modern CSS is based on the border-box
outline definition where the *outer* dimensions are defined and
not the *inner* dimensions.

Bootstrap, Foundation and ExtJS 4 use the modern box sizing
"border-box". This is the default now.

ExtJS 3 CSS is based on the "old" content-box definition. Since
CMS still uses ExtJS 3 we need to move ExtJS elements back into
the former box-sizing mode.

This patch sets box-sizing back to the previous content-box for
input fields. Most dimensions in other widgets and elements are
calculated with the help of JS and not based on CSS itself. Thus
.x-form-field should be enought for the start.
