add Interfaces to menu system, in the current setup this is the only dynamic item. May need an easier hook in the future, but or now this works fine

changed post handling for apply button.

Awful fix, but works for now.  The package system will be
removed anyway...

While there, clean up the copyright headers into a consistent and
readable style.  Claims that we `strip' copyrights are funny.  :)

- extend menusystem ( documentation on our wiki )

* initial implementation for base\menusystem.
* copied in some of the template parts from the legacy system after cleanup html code.

This is not the fix I have been meaning to push, but openssl_encrypt()
and openssl_decrypt() are too low level.  They do AES-256-CBC, but not
key derivation as well as salt and IV handling.  Getting this 100%
compatible with OpenSSL was the blocker then.  Also, experts have said
that the cipher should not be used anymore, adding more annoyances as
this config output does not have a version information prefix...

Added profile option to check_reload_status (configd), measured framework overhead, current max processing for the daemon is about 6200 req/s on my macbook. ( limited by socket.accept, if needed we could implement another dispatch method in the future)

Simple implementation to use the backend service from the frontend implemented.

While there, "maybe" copyright translates to "yes" copyright.
If someone wants to oppose this, feel free to verify each code
line and submit a pull request to remove those two statements.

We do not want to use OpenSSL from base and it may go away at
some point as well, breaking e.g. this page.  Instead, use the
internal tools or the OpenSSL plugin.  More of this on the way.
