CMake: cleanup, project generation and other improvements

- Use EXCLUDE_FROM_ALL for FuzzyLite and GoogleTest to avoid inclusion of unneded headers and libraries into installers.
- Set minimum CMake version only in main CMakeLists.txt
- Set project name only in main CMakeLists.txt
- Visual Studio: add assign_source_group function to generate proper filesystem tree
- Visual Studio: set PROJECT_LABEL so generated projects have same names binaries on Windows
- Visual Studio: enabled USE_FOLDERS for projects grouping. This also possibly affect other IDEs.
- Added add_subdirectory_with_folder function to make sure 3rd-party libraries are affected by USE_FOLDERS.
