Ticket 1101, phtml|php5|php4|php|cgi|pl|exe|com|bat|src| will be hardcoded
additional you can set more extension in settings extended in field rename_file_types
rename_file_types now is a blacklist and will no longer be renamed to .txt
update admintools modules to work with SecureForm Patch from NorHei
