Add option: Random number or string to filenames when tables have same name

[JoeBlackSecurity]

Some idiot before me dumped a massive DB (120gb dump file) with multiple tables that have the same name, into the same file. Dumping with this tool works, but overwrites the previous tables when extracting. I don't know sh at all, or even bash really, but I ended up changing it to bash and throwing $RANDOM until I got it to add a random number to the filename.

EDIT: Looks like it dumps the same table in the dump file multiple times. Not each file.
