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:withLevel:] method.

[DDLog addLogger:[DDASLLogger sharedInstance] withLevel:DDLogLevelInfo];
[DDLog addLogger:[DDTTYLogger sharedInstance] withLevel:DDLogLevelDebug];

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