Now, if the back-end dbms type has been identified by the detection engine, skips the fingerprint phase.

Major code refactoring and commenting to detection engine.
Ask user whether or not to proceed to test remaining parameters after an injection point has been identified.
Restore beep at SQL injection find.
Avoid reuse of same variable in DBMS handler code.
Minor adjustment of payloads XML file.
