Refactor Networking, Authentication, Fix TableView

- All DelugeClient networks calls were refactored to use PromiseKit
- All network calls now check the Deluge API for errors
- Added connection and authentication functions to ensure that credentials are always refreshed
- Fixed a crash that can occur from TorrentInfoTableViewModel changing the amount of rows without notifying the tableview
