Maya: 1. Rebuilt HelgaLauncher. Modified helga_launcher.py to insert custom pathes at the beginning of environment variables and append their old value. 2. Modified userSetup.mel to insert userSetup path at the beginning of sys.path instead of the end. 3. Modified global_variables.py to have MAYA_USERSETUP_PATH last in MAYA_SCRIPTS_PATH_LIST to have it inserted as foremost as possible in the environment.
