table prefixes

For a few reasons my dev tables and production tables use different prefixes. I was managing by doing a search and replace on the SQL each time, but it became boring.

I added a couple fields in the admin form and modified very slightly a couple functions so now I can choose to rename the prefixes in the generated SQL file.

Regards!
