FS#2288 - Importer for data from Plesk control panel (first INCOMPLETE version, see bugtracker for status)

Bugfix: remoting lib field validation "ISINT" differed from tform validation and leads to 0 values treated as invalid
Bugfix: remoting lib did include_once instead of include at form definition files, that leads to malfunction when using multiple definition files at importing and actions like that

added tmp_vars for login + password_reset as replacement for hardcoded language non-neutral expressions

- Bugfix: changed "Return-Path: $form" to Return-Path: $from.

Bugfix: Spaces need to be deleted before cron save, because they are IGNORED on validation but lead to a non-functional cron.
Storing minute / hour / etc. values like "1, 23, 26" (with spaces) is allowed in validation and interface but leads to a BLOCKED crontab file and to non-functional crons of the whole web user.

This option can be enabled under System > Server config and is named "Web folder protection".
