v2.5.12

This release fixes some regressions introduced in OracleDB support in 2.5.11.
Specifically, closing a cursor caused an ORA-01002 exception to be raised
in some scenarios.

Further fixes include:

• support for dropping "in use" databases in OracleDB and SQL Server (must disconnect first)
• corrections in how the last insert ID is fetched on SQL Server
• re-use of parameters bound to an sqlsrv statement via bindValue()
