Fixed #19097: Admin2 reverse object relations tab does not include hidden objects
Fixed #019030: Improve checking for variable on fetch method, ezcontentobjecttreenode.php
Added support for deleting packages.
md5sum() should only attempt to process files, so added a check 'is_file' to prevent a php-error that will be thrown if $file is a directory and not a file.
Fixed an undefined variable error in ezpClusterGateway
'is_file()' calles 'file_exists()' internally, use only 'is_file' instead.
Use $cli->output instead of $cli->notice
