Rebooting...

I'm fairly certain either the json lib is not playing nice, or we are forcing it to do something bad.

[lbussy]

Currently easily tested by refreshing the About page a few times.

Have added PR #84 which will help with this - but that PR should only be merged after we are done testing.

[lbussy]

This is trending better (maybe the BLE changes?) but still not perfect. Happens after about 6-7 refreshes of the About page.

[lbussy]

This is as good as it gets. AsyncTCP + ESPAsyncWebServer is a hot mess. We've used a fork of them both with some key things fixed. It runs about 9 minutes on the about page hammering a reload every 10 seconds. This last PR re-times the JSON requests to avoid piling up a bunch of requests at once.
