FS#3632 - Adding websites with remote API is broken in 3.0.5.4p3 release.
Missed to commit one file for: FS#3634 - Add option to disable statistics for a website

- Merged language files

- Create md5 sums of all files at install and update.

- Added warning in the interface when a path for a shelluser is set that is outside of the website docroot.
- Added security settings feature to allow the root user of a server to control most aspects of whet the admin user of the controlpanel is allowed to do in system settings. This is especially useful for managed severs where the ispconfig admin user and the root user of the server are different persons.

Removed backup_dir_mount_cmd option from Sysstem > server config. The option has been replaced by a script /usr/local/ispconfig/server/scripts/backup_dir_mount.sh. If this script exists, is exacutable and is owned by the root user, then it will be executed upfront of the backup jobs when the option "Backup directory is a mount?" is enabled in server config settings.

- adjusted PHP settings regex to allow |, (, and ) (like in "error_reporting = E_ALL & ~(E_NOTICE | E_DEPRECATED | E_STRICT)")

- autoselect password if you use "Generate Password" function (saves a click if you want to copy the password).

- Fixed "no_domain_perm" error when trying to add proxy directives for subdomains or alias domains (nginx).
