Render loop

• engine alerts and user input drive the loop
• spawn a blocking_task to read in events and communicate them to the main app task via mpsc
• main loop selects on events rx and engine rx

Priority

• show torrent metadata:
  • name, info hash
  • start time, run duration
  • storage info:
    • torrent size
    • number of pieces
    • list of files with sizes
• gauge for torrent progress
• thruput rates (dl, ul, protocol): what to use?
  • sparkline: simplest, can we add labels?
  • or bar chart for more detail?
  • or maybe chart for most detail?

Requires new APIs. Might be deferred until after MVP.

• show completions for each file
