SSL libraries (libeay32.dll, ssleay32.dll) sometimes fail to load on Windows if they are not in the same folder as SlicerApp-real.exe.

This commit makes the SSL libraries installed in SlicerApp-real.exe's folder (c:\Program Files\Slicer 4.7.0-2017-04-20\bin) instead of lib folder (c:\Program Files\Slicer 4.7.0-2017-04-20\lib\Slicer-4.7\ssleay32.dll).
