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
  * 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
  * 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	new	major		gps
