YTDT version 1

This is just the initial release version 1 of Youtube Downloader Toolbox.

It has only basic features but still accomplishes the goal of automatically downloading new youtube videos from channels added to a watchlist, as well as removing things from the watchlist.

Known issues:
- The edit button does nothing currently. It will eventually allow you to change the download path. Maybe later on other saved settings specific to the channel as well.

- Youtube's website changes constantly and it makes scraping content annoying. This means when you go to add a channel and it shows 'unable to retrieve videos', or subs, or the channel handle, etc that means the scraping method I'm utilizing has failed to find something because they changed the website. As long as the channel ID and the channel name is found, it shouldn't matter or break anything.

- The download and checking services are off by default, which means you will have to press them on initially which is probably bad design. I'll make them on by default eventually.

-When you X the window to close the program, it minimizes to your tray instead. I personally like this feature, but unless you know it will do this beforehand, you probably expect the X button to close the program... In the future I'll add a message for the first time the X button is pressed to alert you about this. And then eventually when I add a settings page, an option to enable/disable closing to the tray if you don't like this behavior.
