Moved Qt project files into src - Use shadow build directory instead of tmp (QtCreator's default) - Moved targets to bin and lib - Build static libraries for ease of distribution - Remove VPATH - Remove gcc options from DevStudio builds - Remove QhullError.cpp and QhullEvent.cpp (empty files) - Do not remove app_bundle from CONFIG - Make -fno-strict-aliasing conditional on gcc version - Added src/qhull-app-cpp.pri and src/qhull-app-c.pri for common settings - libqhull.pro: Comment out -Wno-sign-conversion - gcc warnings need fixing. Does not build with gcc 4.4 and warn_on - Moved projects/debian to src/debian. Needs reorganizing
