[2.0] Fixed and added some missing/wrong docblocks. Renamed Assigned to AssignedGenerator as scheduled to be renamed.

[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] More fixes to EntityGenerator. Coding standard fixes and improved error reporting on invalid arguments provided.

[2.0][DDC-459] Moved Doctrine\ORM\AbstractQuery to Doctrine\ORM\Query\AbstractQuery, which is compatible with Doctrine Coding Standards

[2.0][DDC-458] Fixed issue with IN () support when providing numeric values separated by comma without spaces.

[2.0] DDC-239 - Added several new mapping validations for duplicate association/field and or column name definitions, and in combination with the discriminator column name.

[2.0] Improving EntityGenerated: added normal doc blocks above annotations(even if annotations aren't generated), adding type hinting, added generation of default values for properties

[2.0] Fixed issue with Cache drivers that in some situations they were not storing the entries. Also fixed bug with queryCacheTTL that was not being considered in a Query.

[2.0] Refactoring code for reading multiple sources of mapping information from ClassMetadataExporter to a new ClassMetadataReader tool so it can be used to read mapping information easily from multiple different sources. This is used for generating repositories, converting mapping information, generating entity stubs, etc. Generally though, it is useful to be able to read the information for some mapping files into an array of ClassMetadataInfo instances without it being bound to the ORM and the metadata referenced by the EntityManager ClassMetadataFactory

[2.0] DDC-318 - Fixed idempotency issues with AnnotationDriver::getAllClassNames() even across multiple instances using the same metadata paths.

[2.0] DDC-283 - Add two events in SchemaTool that allow to hook into the generated Schema representation, possibly modifying or reacting to it in userland or extensions code.

[2.0] Renaming orm:generate-entity-stubs to orm:generate-entities to be consistent and fixed a few bugs

[2.0] Refactoring AnnotationExporter code to a EntityGenerator tool which is used now in orm:convert-mapping to generate annotated entities and also used in orm:generate-entity-stubs for generating entity classes and properties/method stubs from mapping information

[2.0] Extracting Doctrine 1 schema conversion from orm:convert-mapping task to a orm:convert-d1-schema task
