Subject: [PATCH] added RCTLog.logToConsole() to force log regardless of
 debugger connection

Summary: This adds an alternative logging method that can be called from native side. `logIfNoLoggingHook()` will pass the message to console only if there's Chrome debugger attached. This new method sends the message to console regardless to notify the developers better.
