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

[2.0][DDC-364] Added Doctrine\Common\Version which provides the current version of Doctrine. Also added CLI tasks for Common and DBAL, since they may vary in the future.

[2.0][DDC-316][DDC-346] Implemented support to first result and max results aswell as different hydration mode support in orm:run-dql task

[2.0] Incorporated CLI refactorings. Added support to namespaces and unlimited depth namespaces. Dropped globalArguments for now, since they interfer in DAG implementation.

[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] DDC-114 - Extend SchemaTool Drop functionality to optionally drop the complete database. Additionally a filter against all existing table is applied to avoid errors due to dropping non-existant tables. Updated Schema-Tool CLI command with optional calls --drop=database --drop=metadata but kept original --drop which defaults to "metadata". Updated documentation.

[2.0][DDC-48][DDC-47] Refactored cache drivers to allow more control over deleting, added namespacing to cache drivers and implemented clear-cache task

[2.0] DBAL cleanups (DDC-46). Proxy class improvements (DDC-19, DDC-39). Started new UPGRADE_TO document for upgrade instructions between advancing Doctrine 2 versions.

[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.
