Goal

Allows loading of Configuration from Plist files, without creating a configuration object up front in code.

Changeset

• Added BugsnagConfiguration.loadConfig() method, which reads from the main bundle's plist. Note that the naming is a required deviation from the spec due to an existing method on NSObject
• Added non-public class BSGConfigurationBuilder which loads configuration options from the plist under the 'bugsnag' key
• Updated BugsnagConfiguration to set the apiKey property to an empty string if it is not a valid value or a string value. Previous behaviour was to keep it as the passed in value, even if the object was of a different type (such as a dictionary)

Reads the following values:

apiKey
appType
appVersion
autoDetectErrors
autoTrackSessions
bundleVersion
persistUser
releaseStage
enabledReleaseStages
endpoints
maxBreadcrumbs
redactedKeys
sendThreads

Tests

• Added unit tests to verify the default and overridden values of configuration options loaded from a plist
• Added a mazerunner scenario which loads configuration from a plist
