- Make sure the correct sys_groupid is saved for web folders and web folder users.

This reverts commit 366decb5.

- Implemented FS#3308 - PATH placeholder in directive snippets (placeholder is named {DOCROOT}, like for nginx).

Fixed issue with shell user creation due to missing parent user and group values in shell_user database records.

removed unnecessary bak-files

Completly same functionality as VHost-Subdomain, not to disable if already existing vhostalias-somains in system.

- Fill IP select fields with IP from correct server even if the user's default web server is another server. Otherwise if the user opens the web form, the wildcard * is selected, and if he changes the tab, the wildcard is saved instead of the correct IP so that the website will no longer work.

- nginx pm settings: values were limited to 3 figures (so max. value was 999), increased this to 6 figures.
