macosx: Load library gracefully
Two key changes in this MR:
- Add detection for heavy-hitting library change notifications and throttle them (< 500 ms)
- Display a blurred loading overlay view on the library view when it is loading lots of content, preventing jumping around of views and items
- Temporarily stop checking for changes until the library state has stabilised, preventing the application from becoming unresponsive
