Show progress bars

User JamesThePlant reports:

can I recommend adding some sort of progress bar or percent indicator when you do that initial film download because I'm here waiting for it to download to my browser and I dont know if it's going well or if it just stopped for some reason

I think this can be generalized to having progress bars in a lot of locations, including:

• When media is first being fetched from server
• When media is being downloaded
• When gif previews are being generated
• When gif finalizations are running
