0.6.2 Engine bugfixes, UI improvements

Wanted to get this build out there for the improved logging and to fix the race bug.   That way, I can tell in the logs if it’s my code or the supplicant.

Thanks to all those who donate, and for those sending logs.   I’m going to prepare actual statistics and data for Google to get the supplicant bugs fixed.

As an aside, I’m really happy with the new Performance setting.  It makes setting complicated options easy for those who don’t know the technical aspects.    One of the first things you learn as a smartphone dev is that most of your users aren’t going to be technical.   I really hope it helps make a difference for someone.
