Fastfile: Parse Config.xcconfig to get BUNDLE_IDENTIFIER

- Replace $(DEVELOPMENT_TEAM) parsed from BUNDLE_IDENTIFIER in Config.xcconfig with ENV["TEAMID"]
- Use BUNDLE_ID instead of hard coded bundle identifier in Fastfile, inspired by Artificial-Pancreas/iAPS 6a46a2a by @Jon-b-m 
- Allows building of different instances of the app by only editing Config.xcconfig.
