Added the LogManagerViewController class
Big Commit!
- Discovered bug with size classes, and decided to hard-code the logVC in LuggageManagerVC.
- Most of the VC in IB use Universal Storyboard. Will fix this when Apple fixes the bugs
- logVC now monitors broadcasts, and can mail the log.
- Added "Are you sure"-alert to remove luggage button
- Added NSLocationAlwaysUsageDescription key to info.plist to support CoreLocation
