The old script had a lot of unused code in it, either stuff that couldn't be configured from OPNsense or dead code.

Revert "(ids) style fix", https://github.com/opnsense/core/commit/aaa0ddafe1179cebc68146bdc3c30b8b90c564b8 can cause "Allowed memory size of ... bytes exhausted", better to set a sane default max here.

This reverts commit aaa0ddaf.

(firmware) add configd "firmware loader" commands to control the contents of /boot/loader.conf.local

plugins can use this call to register new bootup parameters, new commands added:

configctl firmware loader show
configctl firmware loader rm <parameter>
configctl firmware loader edit <parameter> <value>

changes in services_unbound_advanced.php

fix translation in firewall_virtual_ip.php

* translation fixes (for example submit button)
* remove some not operators
* make short echo tags look more like a template

Relative redirect is used almost everywhere, but to be honest
