Feature: Vhost templates

Reworked the initial implementation by hpmewes (https://github.com/Froxlor/Froxlor/pull/233) with
- bugfixes all over
- added support for apache and lighttpd also
- added an update sequence (instead of only modifying froxlor.sql)
- added english language variables
- added missing parts in admin_vhostsettings.php
- added parameter replacements as available since PR 244
