DBAL-50 - Fix bug in Postgres Platform not handling index column names that are comming from pg_attributes correctly

DBAL-50 - Fix two bugs occuring when new index handling is mixed with ORM (which produces an additional set of very long automatically generated identifiers) in automatic identifier name generation.

DBAL-50 - Explicitly add an index for each foreign key added to a Schema\Table instance. Removed code to FixSchema based on foreign keys, since assumptions now dont apply anymore. Refactored algorithms to check for duplicate or potential overrule indexes into Schema\Index classes, added tests and unified Table API handling these conflicts

Fix bug in Oracle Schema/Platform detection of DateTime vs DateTimeTz type and disable a logging test that breaky MySQL testsuite.

DDC-684 - Fix flaw in build process, DBAL PEAR package now does not contain Common code and just adds a dependency on the PEAR channel. Additional full package is generated into dist/

DDC-765 - Fix console by converting DBAL Symfony\Components to Symfony\Cpmponent as done for ORM package before

DBAL-39 - Changed SQLLogger again, the recent change disallows to log a failed query, however adding a lastexecuted query would add additional overhead (last params and types would be needed to). So now each logger has a startQuery() and a stopQuery() method. Additionally the logger now gets passed the array of types.

DBAL-37 - Fix PostgreSQL Platform not supporting changes in Autoicnrement during ALTER TABLE generation

DBAL-33 - Added flexible DateTime type that can be used as replacement when variable date/time parts are returned from the database, for example with PostgreSQL TIMESTAMP(n) and TIME(n) types

Fix for both DDC-710 and  DDC-693, added many tests for null conversion and additional tests for the empty value conversion

Apply array_change_key_case in MysqlSchemaManager::_getPortableColumnDefinition() and adapt further code to work with it
