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
it looks safer to make all paths absolute.

(openvpn) refactor openvpn_get_cipherlist and openvpn_get_digestlist, fix compatibilty with both --show-ciphers outputs

Suggested by: SimonB

Since we weaved the latter into the former, we can now get rid of
the transition code.  The behaviour doesn't change.

This does:

o Enable/disable all text as opposed to confusing icons of
  checkboxes.  Also mark them as "primary".
o Make the info button a pencil / edit button as we can modify
  data from there.
o Minor cleanups.

Missing:

o Removing the toggle buttons for each rule (the edit button
  is sufficient).  Haven't done this because the rowtoggle
  mechanism is probably better adapted by @adschellevis.
o Maybe move the enable disable all buttons back to the bottom.

There is no need to visually overload the field descriptions with
stop chars like a slash, the help is sufficient in explaining that
multiple networks can be used and the chances are high that most
will only ever use one network here.

Camellia can only be used with IKEv2

While there also get rid of the need for a /usr/ports dir (this will
make tools.git crash and burn for sure.)

add camellia to cipher list
