Subject: [PATCH] - Added new web folder named private to web folder layout. The folder is intended to store data that shall not be visible in the web directory, it is owned by the user of the web. - Changed ownership of web root directory to root user in all security modes to prevent symlink attacks. - Apache log files are now owned by user root. - Improved functions in system library.
