Self-Hosted GPS Tracker

Sep 27, 2015

v 1.5
- Allow GPS update interval down to 5 sec instead of 30.

v 1.4
- Tolerate devices which sometimes send GPS updates 1 second too early, such as HTC One Mini.

v 1.3
- New option: add a timestamp to each HTTP request. This is needed for mobile data networks which can suffer from high latency.

v 1.2
- New feature: display "Last location sent at (datetime)" and server response (OK if HTTP 200, otherwise it's considered an error)
