FindHome should report correction applied

[George Silvis]

One concern I have is that the gear sometimes skips. The recovery for this is to send the dome Home. If it were to report the correction applied, then examination of the log could tell me how chronic is the problem.

In the code it might look like in HomeSensor.cpp

void HomeSensor::foundHome()
{
std::cout << "foundHome. Correction applied: "
<< settings->position - motor->getCurrentPosition()
<< std::endl;

Should this be submitted as a pull request?
