Division by 0 in ServerModeReader::handleProgress

In the function ServerModeReader::handleProgress, on line 420:

int progress = m_progressStepMinimum

+ (((max - min) / (cur - min)) * (m_progressStepMaximum - m_progressStepMinimum));

we can have a division by zero when cur == min, this has happend to me when loading a very big cmake project. In addition the formula looks wrong to calculate the progress, looks to me it should be (perhaps using float instead):

int progress = m_progressStepMinimum + ((cur - min) / (max - min)) * (m_progressStepMaximum - m_progressStepMinimum));
