tvOS web logging

This adds an option to debug libvlc using the web interface by calling http://ip-address/debuglog

To achieve continuous updates to the libvlc log in the browser, the web server was extended.

Why was this change done and how is this related to #184 (closed)?

@ePirat vlckit 184 and because modules would fail and produce errors and it would just try the next module and work fine. So the user would get an error message even though there was no error

You can reference issues in other projects like so: videolan/VLCKit#184 (This will get linked correctly by Gitlab: VLCKit#184 (closed)).

Do you have a example of where a module produces an error even though another module might be able to handle it fine? Because I think this should never happen?

@ePirat ah merci :) didn't know that you could do it like that. @tguillem probably has some. I just tested with some old subtitles errors. TBH as you can see from my comments I also figured that the errordialogs shouldn't come out of libvlc if we don't want to present them but they're needed for the log UI in VLC as well from what I understood, also they're not translated
