created a method to find QSettings (settings.h) and stopped it from leaking.
The leak looked like this...
==7800== at 0x4C2726C: operator new(unsigned long) (vg_replace_malloc.c:230)
==7800== by 0x64FD232: (within /usr/lib/libQtCore.so.4.5.0)
==7800== by 0x64FDB62: QSettings::QSettings(QString const&, QString const&, Q
Object*) (in /usr/lib/libQtCore.so.4.5.0)
==7800== by 0x4738E5: PfPvPlot::setData(RideItem*) (PfPvPlot.cpp:361)
It offers to split at any time gap over 30 seconds and also at any interval.
If the time gap is over 5 minutes it defaults to checked, otherwise it
defaults to unchecked.
Anywhere you check, it will split the ride at that point overwriting the or
original ride with a shorter one and creating new rides after the split points
The original would get renamed with a .bak so it could be recovered.
