Updated all .torrent files to include:
```
"announce": [
"udp://tracker.leechers-paradise.org:6969",
"udp://tracker.coppersurfer.tk:6969",
"udp://tracker.opentrackr.org:1337",
"udp://explodie.org:6969",
"udp://tracker.empire-js.us:1337",
"wss://tracker.btorrent.xyz",
"wss://tracker.openwebtorrent.com"
]
```
Removed dead trackers from the list.
- Fix bug where new install was relying on the migration to run on
startup to fix up the default config
- Moved save/load functions into state.js
- Removed exported getInitialState, getDefaultSavedState since that's
leaky. The state module should take care of that.
