Unsuccessful attempt at fixing "dismiss"/"close manager" buttons in ACL editor; non-breaking change to template API to allow plugins to add "normal" sidebar widgets in addition to the special "raw" block type, specified as the third parameter to $template->sidebar_widget(). Defaults to false, which is old behavior; new behavior (enabled by passing TRUE as the 3rd param) means that the content of the block is primarily block-level links.
