Checkboxes and radiobuttons not clickable when they hold a [for] attribute

[Paulus90]

After updating to castlecss-forms 1.0.12, checkboxes and radiobuttons are not clickable anymore when they hold a [for] attribute (on the label element). This is due to the presence of 'pointer-events: none' on the element. A possible fix could be to check if the label element has a class of '.input-control' and not apply the above style rule if this is the case (...:not:(.input-control)....).
