[2.0][DDC-359] Adding some tests for CliController and fixing bug with empty option value .i.e "--option="

[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-366] Fixed. Fully qualified names were borked in the lexer as well. Tests didnt catch it because of unfortunate namespace constellations. Fixed now.

[2.0][DC-460] Refactored cache bulk deletion methods to use driver specific features to retrieve list of keys. Also, refactored tests
so that all methods are tested for all drivers.

Removed:

- Doctrine\Common\Cache\AbstractCache::count()
- Doctrine\Common\Cache\AbstractCache::deleteAll()

API Changes:

- Doctrine\ORM\AbstractQuery::getResultCacheId() now public

Bugs fixed:

- Doctrine\Common\Cache\AbstractCache::deleteByPrefix() was deleting _every_ key in cache

[2.0][DDC-183] Fixed issue with Annotations parser failing on identifiers that matches with token types.

[2.0][DDC-171] Fixed (second attempt). Some other cleanups. Performance fix for mock Statement used in hydration performance tests for more accurate and better results.

[2.0] More refactorings in Annotations parser and DQL parser. Now they only use constants instead of string processment

[2.0] DDC-78 - Added support for context specific information in Annotation Parser Syntax Error Exceptions.

[2.0] Added test that shows AnnotationParser only parses string literals with double quotes, wheras single quotes throw an Syntax Error. Removed debug output on failure for a proper syntax error exception.

[2.0][DDC-22] Fixed. Also cleaned up association handling. More to come: exception refactorings, proxy simplifications (single proxy class, not two).

[2.0] Small refactorings on the cache drivers. Introduced flag to control whether the cache driver should manage the cache keys since this is an advanced feature that is not always needed and can have negative side-effects (higher probability for cache slams).

[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] Refactored classloader architecture. Renamed ClassLoader => GlobalClassLoader. Introduced IsolatedClassLoader that is suitable for participating in autoload stacks. Added 2 example entity classes to the sandbox with 2 xml mappings and 2 yaml mappings. Simplified sandbox setup.

[2.0] Streamlined result structures. Hydration improvements: Small overall improvements, large improvement for (joined) fetched collections (~60%). 

[2.0] More cleanups for recent lazy-loading implementation and minor object hydration improvements and cleanups. Collection refactoring part I for ticket #2352.

[2.0] Commented Memcache test since it was throwing a fatal error if module is loaded. It requires a memcache server config to be able to run these tests

[2.0] Fixed array tests by removing tests for ArrayCache specific methods from the tests of other cache drivers. Some general API work on the cache interface.

[2.0] New Annotation API work: Simplifications, changed namespace separator to match the one of PHP, adjusted Lexer to swallow any * characters outside of a string value to be more forgiving when it comes to formatting.

[2.0] Moved cache drivers to Common package. Added new annotation parser implementation to Common package. AnnotationDriver in ORM not yet migrated.
