198	more efficient and robust track logging	Martin Kolman	Martin Kolman	"* current setup
  * currently the whole track is periodically dumped to a GPX file
  * that means that the longer logging is running, the longer takes it takes to save the tracklog

 * efficiency '''done'''
  * just save the increment to a simple text file with one line per point (CSV)
  * periodically save small increments (say 10 lines every 10 seconds for 1 point per second logging frequency)
  * once logging is stopped, convert the simple text files to GPX
  * check on startup if there are some files left from the last time (in case modRana couldn't exit cleanly)

 * robustness '''done''
  * save to two files so that if one gets corrupted (eq. modRana or device crashing while the file is being written), there is still one left"	enhancement	closed	major		gps		fixed
