Quality of Life Changes

[frxctura]

This PR adds:

• Newlines to the "All tasks finished." message.
• Invoke MessageBox inside of ADB.cs for the "In place upgrade has failed" as this can cause exceptions during debugging.
• Not reload the gamelist if one is inside of a filtered list.
• Remove StandardINput.WriteLine & Flush as we already hand over the command to ADB via "Arguments", making Input redundant.
• Cleaning up the code for the dropdown categories.
• Cleaning up the code for the Trailers.
• Clean up the progressbar code, it should function the exact same from testing.
• Check if the rclone we are killing is part of the parent process (in this case: AndroidSideloader.exe), this will make it so that we do not kill unrelated rclones.
• Optimize the code for getting the thumbnail paths.
