Ext4: improve 401 error message
json-login: If identity or credential are missing don't throw exception, report proper error
change error texts as these will be shown to the user

and translate them...
port some onContentReady to onElementReady

- improves performance as much less dom queries have to be done
- also add some names to anonymous functions for easier profiling
don't recursively call onContentReady

this makes profiling much easier as we don't get a deep stack.
Performance shouldn't change
don't call getWidth twice, cache it

getWidth might be a expensive operation if it triggers a reflow
performance: don't create img in javascript, only alter the src
ViewAjax: use layout auto to avoid inline width style

required for responsive layout, has been solved previously using width: auto !important
Lightbox: use onElementReady

avoid quering for kwfLightbox
performance: avoid creating Ext.Element, use dom node directly
improve onElementReady performance

- add variants: onElementShow, onElementHide, onElementWidthChange
- call for deep elements last and only once
- use jquery for selecting (improves performance)
- add benchmark numbers
add option to defer onElementReady

this defers initializing that element for 100ms after load
performance: defer init of more components
