Description of the Issue

When I start the editor, I usually need to fix something really quick. The current update behavior makes it annoying because it interrupts my actions. I suggest a couple of enhancements to fix that.

Steps to Reproduce the Issue

1. Start the non-latest version of the editor and try doing some editing you get paid for.
2. The editor interrupts your work by displaying the update window.
3. You agree to update and click left mouse button 10 times, restart the editor.
4. Try to remember what you were doing when you started the editor, can't remember, go away crying.

Expected Behavior

1. When a new version of the editor is built, there is a silent installation option implemented in the setup file.
2. User starts the non-latest version of the editor.
3. Unseen by the user, the editor checks if auto-update is enabled as a background task.
4. Unseen by the user, if auto-update is indeed enabled, the app checks for an update.
5. Unseen by the user, if there is an update available, the editor downloads the file in the background thread.
6. As soon as the user is done and closes the editor window, the editor asks if user wants to install an update.
7. If user agrees, the editor closes its window and launches the setup with the silent update option - no additional windows, no click, nothing.

Actual Behavior

1. User starts the non-latest version of the editor.
2. The app checks for an update.
3. There is an update available, the editor shows the update dialog.
4. User is frustrated and annoyed.
5. User agrees or doesn't agree - anyway, he/she has to interrupt his/her work and click buttons.
