File path built more efficiently and now allows an arbitrary length. Prevented strdup() of NULL if path too long. Similarly prevented fopen with a NULL file name. Added function to determine Windows absolute paths properly. Fixed numerous issues that were caused by including Windows system header due to conflicting names. Generally a CMPP_ prefix was added as a "namespace". Also used the standard C bool type instead of defining one.
