Add informal protocol so that image browser delegate is called back on single click on resource in icon view
Show warning or error alert panel on thumbnail in icon view when cell was (left-)clicked and not when cell was selected

Safeguard against accessing arrangedObjects array at illegal index
Ensure that Quick Look works when invoked through contextual menu and app is not active

Alleviate a warning in IMBFacebookAccessController when -Wundeclared-selector is enabled.
