New mod menu (video)

A new menu with the ability to download modifications to our game. It is currently in early access and will be available in version 0.948b. Of the innovations (yeah, it's video):

- A more intuitive download manager. Display and multithreaded loading of modifications. 

- Notifications. 

- Displaying screenshots of modifications (so that you don't download the modification blindly) 

- The ability to delete modification directories using the mod manager. 

- Separation of installed modifications and the existing library. 

- Displays the time of the last update of the modification, as well as whether the update is available to you personally. 

- The game restart button. 

- The ability to update/check modification files without downloading unnecessary files. 

And also a lot of other things...
