Use Log Level per Logger

If you need a different log level for every logger (i.e. if you have a custom logger like Crashlytics logger that should not log Info or Debug info), you can easily achieve this using the DDLog +addLogger:withLogLevel: method.

[DDLog addLogger:[DDASLLogger sharedInstance] withLogLevel:LOG_LEVEL_INFO];
[DDLog addLogger:[DDTTYLogger sharedInstance] withLogLevel:LOG_LEVEL_DEBUG];

You can still use the old method +addLogger:, this one uses the LOG_LEVEL_VERBOSE as default, so no log is excluded.
