- added possibility to execute mkdirpath, file_put_contents and file_get_contents as unprivileged user, partly implements #5417

- fixed warning in chmod

- moved jailkit functions from bash files to system library

add optional arrays for service-name to function system->getinitcommand and also a parameter to check if the current service exists (mandatory if you use an array)

FS#3897 - backup - delete unused file (interval = none), fixed mail-backup delete, moved mail-function for failed mounts/umounts

- Fixed: FS#3710 - Bug with PHP-FPM configuration since 3.0.5.4 Patch 4
- Fixed wrong function calls in system lib.

- Fixed a problem with restart of services due to the fact that Ubuntu has upstart and systemd installed, but only upstart is working without errors.
