The word "Weitere" implied that there are already people in the meeting so I replaced it with "andere". 
I also made line 775 gender-neutral as "der Einzige" would technically only refer to males which isn't an unusual thing to do but some people might consider it discriminatory against women.

Fixed same mistake again as it was in there twice, also made the phrase a bit shorter as otherwise it wouldn't fit in the screen.
Changed "Wollen" to "Möchten" as it's more polite.

sie -> Sie
ihre -> Ihre
100% -> 100 %

Fixed very small mistake in the programming. I don't need to sign the CLA for this, do I?

simple Typo

Just checked and Firefox calls the button "Erlauben" in their official German translation while Chrome, Chrome on Android and Opera call it "Zulassen".
"Host" should now be translated consistently
Added two hyphens because "meeting password" is one word in German

This commit fixes a few translation errors, especially in the
kickParticipantTitle.

Change inaccurate translation of toggle camera.

Fixed a lot of punctuation and spelling mistakes. "Speaker" means "Lautsprecher" in the context of audio devices. Rephrased a sentence to make it sound better.
