Update Missing translations

First step is to switch the current status page away from legacy smp.
(work in progress)

(legacy) kill "interface cache", let's not try to cache things that may change during the session... all for saving a ifconfig call.

related to, https://github.com/opnsense/core/issues/451 (try to avoid smilar issues)

(legacy) style cleanup rc.newwanip, don't try to loop back to configd if not needed. loosly related to https://github.com/opnsense/core/issues/451

(legacy) remove caching of filter interfaces, likely suspect of https://github.com/opnsense/core/issues/451

(legacy) fixup code style for filter.inc before performing actual change (missing curly braces, indents, etc)
