On a Detected flash

[LibreNews Server] [ERR] Encountered an exception while processing a flash: name 'thread' is not defined

[lisbonjoker]

Tornado is not getting the real IPs from nginx and it's getting two errors when a new subscription appears and when a new flash shows up. resulting in not sending browser notifications.

@lisbonjoker looks like you just need to make sure the data send to tornado is wrapped as string not bytes. Prob leftover 2-3 conversion crap. TypeError: can only concatenate str (not "bytes") to str
