Does this supersede #102 and close #99?

[erisu]

#102 is only based off the user agent string which can change at anytime and also users can change it on their own. Also this uses browser platform code. Browser platform code lacks ability to grab UUID and other things so its not really a good solution for electron support

In short it will close both.

lgtm -- but travis tests are reporting eslint errors that should be resolved.
