[2.0] Fix Fatal errors in unused classes that crash the testsuite when running PHPUnit with coverage-whitelisting of complete Doctrine directory.

[2.0] Fix Tab Formating in ParserResult class, added doc-comments and fixed a missing variable initialization error for certain query special cases.

[2.0] DDC-109 - Fixed another warning in SchemaTool with inverse join columns and unique constraints.

[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.

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

[2.0] Fixed DDC-63 and DDC-106. Oracle tests for SchemaManager need further tweeking, marked as skipped for now.

[2.0] DDC-91 - Enhanced SchemaManager::listTableIndexes() considerably. Add primary keys to the index list, add a bool flag primary to each index, add an array of columns to each index. Moved a test to SchemaFunctionalTestCase to check that every database (Mysql, Pgsql, Sqlite, Oracle) returns exactly the same data from this function.

[2.0] DDC-84 - Added increment alter table / update schema tests for Oracle Platform - Fixed a simple bug in Postgres Tests.

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