Updates to get file-sizes out of zipr under control.  should now work with .exe's, .so's, and executable .so's.  note:  assumes that if entry_point==.text's address that the .so is not-executable (because the .text is the compiler's default entry point, indiciating the user did not specify an entry point.)  May not be a rock solid assumption, but it should be OK for 99.99% of all programs

made work on CGC machine.  Added prelim options for linking it callbacks from a separate .exe file.  added verbosity flag.
