* Updates:

- Notify manager about all available update methods at once, so the priority
     system works and it doesn't only update via HTTP
   - Start router update download at startup if available
   - Only check plugins when core version increases, not decreases, so we
     don't update plugins when downgrading
   - Limit length of URL shown on summary bar
