Upgraded error layout to HTML5.
KWF now uses "Pure" as CSS framework. Moved KWF specific style rules to kwf.css, which is now included by all layout views.
Restyled the framework runtime error debug messages.
The CSS class for form errors was renamed to .kwf-form-error for consistency with other KWF styling.
Override of Pure's font color on form label elements to darker.
Added Pure styling to test case views.
Runtime errors from framework are now being handled in a better way of JS AJAX class. Debug info are shown in a K.Dialog.
