[2.0][DDC-354][DDC-425] Fixed. Encapsulated SQL logging better in the DBAL. Added binding types to DBAL mapping types as well as using these binding types in the persisters. Query and NativeQuery now support PDO binding types as well as DBAL mapping types when binding parameters.

[2.0] DDC-197 - Fix for OCI8 returning CLOBs as OCI-LOB instances, was it that easy? The test suggets that inserting clobs is not even requiring the temporary syntax anymore.. Great!
