Update beck-online.js

1. beck-online.js
Added support for beck-online "Leitsatzkartei" LSK (database of leading records), i.e. scraping of articles where beck-online does not have the article itself but only information about the article

2. juris
Added new translator for the German legal database Juris.
Adding versioning notes is not quite necessary when using git (particularly for translators), since your commit notes should pretty much cover any changes you want to highlight.

Technically, I think it's still an interesting question about copyright. Generally translator patches are relatively small fixes to original code, so there's not much to copyright intellectually. If someone wanted to argue, I would say that your contributions introduce a reasonable chunk of code that is not derivative, so you probably would be entitled to some copyright. Don't know how that would be done (I guess a separate comment block for your part of the code). But it's great that you don't care, because I don't think there's general interest to figure this out. :-)

You should add a proper copyright  line to the new translator you're submitting though. Would be great if you could use your actual name, though I guess it's not a requirement.
