Issues with newer version of Tornado when installing with pip.

[br1guy]

There seems to be an issue with a newer version of tornado that automatically gets installed when installing tailon with pip. The issue seems to be with tornado 5.0.0. Manually installed version 4.5.1 of tornado and had no issues. There is an issue with it complaining about the number of arguments. Not sure this is a tailon issue exactly, but it is what gets installed when installing tailon.

Running this command: /bin/tailon -f /path/file.log --allow-transfers -b *:8805

Gets this error message:

Traceback (most recent call last):
File "/bin/tailon", line 11, in

Hi. Thanks for the catch. I just released 1.3.1 that pins tornado to <=5.0.0. This issue in sock-js needs to be fixed before tailon can support tornado 5.x.
