More fixes for you, from me, xoxo

• An exit queue has been added that will finish downloading any media when the main form closes. This should allow you to download files while an update is pending.
• The default values for the video format using the quick downloader is now bestvideo+bestaudio/best (or just bestvideo if no sound is enabled). This should allow you to download videos without sound on out-of-range qualities/formats, if supported. (hint: the best option was in this category. how did i know? i found a video of a cute as fuck red panda and tried to download without the sound, despite the fact you can download just the video. i did fix it. you can thank that red panda (and not the person who added that annoying music in the background), otherwise i wouldn't have ever found out.)
• The "Format download options" on the extended downloader was moved out of the formats tab. I know, I know it's weird, but it feels better this way.
• Authentication now has an option for a cookies file and a cookies from browser input. It requires you know what it does to work.
• Additionally, the authentication has been updated to use a SecureString instead of string. It's a little more secure, but there's genuinely no way I know of to securely transfer it to yt-dlp. If there's a way, tell me please.
• CopyData has been worked on.
• Logging and Exceptions have been updated, they're better now.
• I still hate Culture-related parsing. Percentage parsing should work regardless of your culture. Sorry, foreigners, I don't think I will ever learn.
• Internal youtube-dl updater checking is all better, now.
• If you have an "estimated" download size and ETA, it should accurately display the download size and ETA.
• Suppress errors works. Who would imagine that your settings work.
• A good amount of back-end work. I don't remember it all, and I'm so smart that I don't explain it on commits so I can't read the summaries to copy+paste them here.

I'm also working on an "extended" batch downloader as well, to go with the main downloader. I'm not inspired to work on it at the moment, but the ground work is there for future me to finish up. I didn't exclude it from this update, that's why the size went up a lil' bit.

Updated the German localization, thanks @uDEV2019
