DBAL-22 - Throw ConversionException if DateTime, Time, Date, DateTimeTz, Array or Object conversions from the Database to PHP fail

DBAL-22 - Make DateTime type the fallback for platforms not supporting DateTimeTz, add test for the later and test for default DateTimeZone

DBAL-22 - Fix DateTime with Timezone handling in Postgres and Oracle by introducing new type DateTimeTz and have SchemaManagers of both platforms detect this type. Added general conversion testcase which made some bugs in Oracle Date Handling and $stmt->fetchColumn() appear

Temporary fix for issues appearing due to DBAL-2 reopening, found an actual additional bug that is now fixed in PostgresSQL Schema Manager
