Native Database Error Codesa

I recently posted to the forums about supporting the returning of the native database error codes in addition to the message that's returned when a Kohana_Database_Exception is thrown.

Ideally to handle multiple DBMS's this would require a conversion between the native error codes and an equivalent in Kohana that is DBMS independent in order to remain DBMS-independent in the application code, rather than wired to handle the codes of a particular DBMS (MySQL in my case)

Perhaps that's too much code-bloat as it would mean the DB code begins to look more like PEAR MDB2 classes?

This functionality will be part of #204.
