fix bug when adding url to refresh file panel after successfull add, validate url, show number of subfolders/items inside a folder when deleting from treepanel, disable properties for urls
Get rid of the get_page_header_stuff kludge. Add a proc to set the portal page CSS for the current layout (using template::head API), to be called from layout templates
allow cases where file storage is readable by the public, add better error handling for failed file/folder move, fix checks on create_url and share_folder features, fix bug in file delete caused by missing param variable
theme-zen now uses blank-master instead of blank-compat. Replaced header_stuff with calls to template::head where necessary to make it possible (except new-portal that needs to be done -portal layouts-)
