[DDC-497][DDC-500][DDC-342] Fixed. Persister polishing and refactoring. More to come for that, but after beta1.

[2.0] Coding Standards fixes, added missing docblocks, removed some dependencies from Common package (in Annotations component), etc.

[2.0][DDC-524] Fixed issue with UPDATE/DELETE statements generating wrong SQL when using Association Paths.

Changed privates to protected and updated setUp to use late static binding. This allows projects using Doctrine2 to use its test cases for testing their own entities.
