* Eliminated initializations for pointers returned by calloc.
* Moved grfio_final to do_init since it's not used after server boot.
* Optimized scripts to return CONSTSTR instead of allocating memory just to return a constant string. Some buildin functions still need work.
* Disabled graph since it doesn't work yet.
