This was a rare race condition during app shutdown where a 'wt-'
message would be sent from the hidden webtorrent window to the main
window after the main window was already closed.
Fixes#373
* Separate hidden window, with its own renderer process, for WebTorrent
(Must be a window. You cannot run WebRTC at all in a Web Worker, and you can't
run it well in a node process like the electron main process.)
* Disabled the create-torrent-modal for now. That gives us a consistent UX
regardless of whether the user dragged files or folders onto the app or opened
the Create New Torrent menu item.
* Main process routes all messages between the main and webtorrent windows.
* The renderer index.js is smaller now (but still too big), with the WebTorrent
interface moved to webtorrent.js / it's own process.
* The UI should be faster now, and should not lag under load.
We got the window to run less JS but now it’s shown by the main process
too soon! This fixes that with a setTimeout.
Perhaps when this issue is fixed
(https://github.com/atom/electron/issues/861) we can remove the timeout.
- make torrent placeholder the exact size of a normal torrent
- make torrent list window minimum size of two torrents
- make window start out sized for 4 torrents
- increase font size responsively
* Download button is a lot easier to read: white down arrow when off, animated and pulsating green down arrow when downloading, solid green up arrow when seeding
* Play button shows a spinner if you click play before a torrent is ready, then an exclamation point if the torrent still isn't ready after 10 seconds
* Drop target shows up always, not just when the torrent list is empty. Lights up when you drag something
* Fixed alignment, the Xs to delete torrents are now aligned with the + to add a new torrent
* Finishes the saved torrents feature!
* Torrents load and save correctly. Poster is autogenerated only once.
* Torrents can be paused and restarted
* Download button indicates state:
- White means paused
- Pulsating green means downloading
- Solid green means finished downloading, only seeding
