Changeset 3167 for code/branches/pch/bin/vld.ini.in

Merged the build system changes from the Gruppenarbeit:

• More Comments (including Doxygen stuff for the config files)
• Removed redundancy between PackageConfigMSVC.cmake and PackageConfigMinGW.cmake
• Option ORXONOX_RELEASE which activates some expensive (build time) optimisations
• Native Visual Leak Detector support (doesn't work for MSVC9 though)
• Added CMake option to disable the console on Windows
