Fixed problems with the wxDb::Open(wxDb *copyDb) not copying in all the different data types required values

Browse Source 
Added Interbase database support based on contributions from Roger Gammans
Enabled the wxDb::TablePrivileges() function for v2.3/2.4
Fixed a bunch of problems with wxDb::TablePrivileges() not working correctly with all databases.
Added the ability to pass in a SCHEMA to wxDbTablePrivileges() that greatly improves the speed of the privileges lookup.
