Rewrote CMakeLists.txt to build qhull targets
- qvoronoi: Deprecated 'Qt' and 'QJn'. Removed from documentation and prompts. These options produce duplicate Voronoi vertices for cospherical data.
- QhullError: Add copy constructor, assignment operator, and destructor
- Add throw() specifiers to RoadError and QhullError
- Fixed additional uses of strncat
- Removed doskey from Qhull-go.bat. It is incompatible with Windows 7
- mem.h: Define ptr_intT as 'long long' for Microsoft Windows _win64 builds. On Linux and Mac, 'long' is 64-bits on a 64-bit host
- Moved include's to top of Qt .pro files. Define $VERSION before $VER_MAJ.
- Name shared library with $VER_MAJ
