Easy GPS logger

1/4/2016

- Saved files did not show up when using USB transfer cable to transfer files to computer unless you restarted your phone; this is arguably an Android bug, but I have implemented a workaround which appears to fix it.
- Fixed an error that sometimes occurred when finishing a GPX file (so the file stayed unfinished).
- Fixed a reported crash on a strange device that doesn't report satellite count (these should now show as '0 satellites' instead of crashing)
