Add SOCKS5 setting on the user interface

I know that it is currently possible to set and use it from the config file, but it isn’t really userfriendly.

My opinion it is that as far people (everyone, even not experts) will feel secure about their own freedom of expression, the better the results of a project as Aether will be.

And so, I think that the “complete” security of everyone, where even the IP can become a sensitive data, should be easily achieved.

Then I’m requesting to add it directly on the interface part of Aether, so users will not need to being able to open folders/files from that maybe could be beyond their knowledge.
