Fixing ensure-production-settings task to not throw an exception and instead use the Output object to output an error

Fixing issue with orm:convert-mapping task and dest-path that does not exist yet as well when reverse engineering from-database

DDC-510 Move Exception for no Metadata Driver from Configuration to EntityManager::create, commit missing MetadataFilter

DDC-510 - Refactored Metadata Driver to be an required option, even for Annotations - allowing to use the specified paths in ORM Tooling Commands

DDC-502, DDC-507 - Changes to how Annotation Metadata Driver is handled in SchemaTool Command, Specifiying Mapping paths is now required for this to work.

[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] 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] 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-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

[2.0] Code cleanups. Preparations for DDC-193. Fixed DDC-399, type configuration remains global for now but the irritating instance methods on the Configuration have been removed. Use Type::addType et al. Added TODOs for naming standards.

[2.0] Added custom Entity repository, DiscriminatorColumn and DiscriminatorMap upport in AnnotationExporter
