Alpha Pre-Release v1.3

This alpha release changed the original policy of patching LD_LIBRARY_PATH.
We used to add an additional path to LD_LIBRARY_PATH but this time we totally changed the way of hacking argv0. We do not use rebuilt ld.so but preload hacking the function named "__libc_start_main" so that argv0 is modified before calling the user's main function.

Changed some other environment vars.
