[FIX #371] Repaired the multithreading setting

 * Previously application crashed every time on processing data using Lari/Habib (2014) surface detection
 *
 * In method WMSurfaceDetectionByLari::properties():
 * WPropInt m_cpuThreadCount = m_properties->addProperty( "CPU threads: ", "", 8, m_propCondition );
 *
 * Yes, m_cpuThreadCount is a member variable of the class. Putting "WPropInt" here is
 * definitely not a good idea.
