Autoreset feature

[vorban]

Two scenarios:

1. Reset a run in progress
2. Reset a finished run

The check for a new game is done via:

private void CheckStart()
{
    if (_mem.GetMenuLevel(0) == MenuLevel.VentureForth && _mem.GetMenuTransitionMode(0) == TransitionMode.AllOut)
    {
        _model.Start();
    }
}

This check could be done continuously and if true while the run is started, then it means we need to reset the run.
If true after a run is done, we could just save the splits and auto start.

An option in the settings of the autosplitter to autoreset (one for reset a run in progress and another for a finished run) would be nice.
