Schema history editor

this release adds a new form for the settings, which will help manage the schema history. yeah.

• File name schema history editor added, it's basic.
• Download ETA has been added to: The progress bar on the quick downloader & the title bar on the extended downloader.
• Arguments finally finished. It doesn't support queuing up another download while one is running, but I hope to add that support later.
• Protocol support for the program was added, the protocol used is "ytdlgui".
• If "mp4" is a selected format, it should download as MP4 now.
• When selecting a schema from a combobox, it will have the index of the saved schema (in the settings) set instead of just the text, so you can scroll up/down from that index position. Just to reiterate: selecting a different schema on the main form will NOT overwrite the saved schema, but if you use a new one it will add it to your schema history.
• Fix youtube-dl verification by extracting the version from the "FileVersion" instead of "ProductVersion".
• Behind the scenes: The c# langversion has been upgraded from 10 to 11.
