Browse all defects in function SlipPlane::calculateDislocationStresses #27

In the function SlipPlane::calculateDislocationStresses, currently only dislocations are browsed and their stress fields calculated. However, other defects may have stress fields too. Therefore, for each dislocation, the total stress field at its position should be calculated using contributions from all defects. Moreover, the class Defect has a virtual function Defect::stressField precisely for this reason.

The function now browses all defects. In addition, the safeguard to prevent division by zero has been placed within the Dislocation::stressFieldLocal function, thus removing the need to check for distances (or pointer equality) in any functions calling the stressField function.
