[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] 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] 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

[2.0] Fixed issue with AbstractFileDriver exporter that was generating files using backslashes instead of dots, preventing the other exporters to work correctly.

[2.0][DDC-92] Fixed. Patch provided by Christian Heinrich. [DDC-274] Started some method renaming. [DDC-142] Fixed (join column names and discriminator column names dont support quoting) [DDC-258] Fixed.

[2.0][DDC-265] Partial support to inheritanceType in AnnotationExporter. Still needs to add the discriminator column.

[2.0][DDC-265] Partial support to inheritanceType in AnnotationExporter. Still needs to add the discriminator column.

[2.0] Fixing ClassMetadataExporterTask to use existing configured annotation driver for given path instead of re-creating it

[2.0][DDC-236] Enhanced unique constraints to support names. Fixed general issues on XML and YAML exporters. Fixed issues on XML, YAML, Doctrine 1.X and Annotation drivers.

[2.0][DDC-122][DDC-97][DDC-98][DDC-147] Refactored metadata mapping drivers by removing the useless PRELOAD mode. Introduced ClassMetadataFactory#getAllMetadata. Classloader simplifications. Old classloaders deprecated. New Doctrine\Common\ClassLoader is almost the same as the previous IsolatedClassLoader.

[2.0] Refactoring some common code in to the AnnotationDriver and creating PhpDriver for consistancy

[2.0] Added functionality to convert a Doctrine 1 schema to Doctrine 2 to help users with upgrading. Lots of other small bug fixes and changes.

[2.0] More work on ClassmetadataExporter and ConvertMappingTask for converting mapping information between various formats
