1. Add cmake BUILD_PYTHON_MODULES option.
2. Rename log options getting functions. 3. py: - pcilib_init_py() - extract pcilib_py_add_script_dir() - pcilib_py_init_script() - extract view-specialized code to pcilib_py_get_transform_script_properties() 3. pcilib_open(): - move pcilib_init_py() to previous position. - add extract pcilib_py_add_script_dir() 4. pcilib_script_s - change hash key. Now it is (const char*) and contains script file name with extension 5. pcipywrap: - Add pcipywrap.h to remove swig generated file complile warnings - remove -includeall swig flag to prevent crash in multi-thread scripts - change set python expetion mechanic
