[2.0] DDC-338 - Changed DQL Parser to comply with ordered collections when they are fetch joined (OMG, thanks to roman and guilherme for the detailed discussion on how to implement this)

[2.0][DDC-316][DDC-346] Implemented support to first result and max results aswell as different hydration mode support in orm:run-dql task

[2.0] DDC-336 DDC-337 - Changed @OrderBy annotation to take a DQL not SQL snippet, restrict it to field names and positional orderings. Changed all test-cases and added a test-case that shows the behaviour for OneToMany JoinedSubclassPersister Managed Entities.

[2.0] DDC-337 - Collections that are fetched through StandardEntityPersister and ordered are sorted by any given ORDER BY snippet. Now only the DQL Parser is missing in this regard.

[2.0] DDC-336 - Support specification of an OrderBy SQL snippet in OneToMany and ManyToMany Associations in Annotation, XML and YAML Drivers

[2.0]  DDC-330 - Fix SIZE(collectionValueExpression) using a COUNT(field) to COUNT(*) because in many to many scenarios and with several join columns a COUNT(fieldA, fieldB) would have been generated, which is not valid sql.

[2.0] DDC-135 DDC-177 Implement missing WITH clause, disallow use of ON clause by throwing an exception

[2.0] DDC-321, DDC-323, DDC-324 - Implemented way to define UDFs from PHP in Sqlite Driver and registered to required default callbacks for SQRT and MOD, allowing functional tests for DQL MOD and SQRT to pass for all platforms.

[2.0] DDC-320 - Fixed Substring across all platforms using AbstractPlatform::getSubstringExpression() instead of the "hand-built" one.

[2.0] Added DQL Functions and Aggregate Functional Test-Case and fixed two small bugs in DQL Parser that came to light, also it seems that some of the functions are not supported by Oracle and Sqlite and some cases of SUBSTRING and TRIM produce bugs on MySQL.

[2.0] DDC-313 - Removed abstracted trigger support, list functions, list users and the platform specific code to generate the queries for this stuff.

[2.0] Fixed proxy classes to not invoke parent class constructors. We never call constructors to reconstitute persistent entities and proxies always represent persistent entities.

[2.0] DDC-312 -  Refactored View support of all platforms a little - Oracle now also supports the retrieval of the sql used to generate a view so that a common datastructure View is a viable option.

[2.0] DDC-302 - Drop convenience methods since their API is somewhat strange, have to think about something else. Dropped AbstractSchemaManager::listTableConstraints() support - since it only returns the names of all constraints, which are already returned much more nicely with listTableIndexes().

[2.0] DDC-125 - Query Hints are now included in both QueryCache and ResultCache - QueryCache now also uses firstResult and maxResults for the cache key - ResultCache was fixed to use "getSql()" instead of "getDql()"

[2.0][DDC-79][DDC-261] Fixed. Also fixed support for deleting objects by reference (getReference() + remove() + flush()) to effectively delete objects without loading them.

[2.0] DDC-214 - Changed MysqlPlatform::geTListTableForeignKeySql() slightly to be performant again, thanks Eric Durand-Tremblay for the patch!

[2.0][DDC-284] Fixed. API polish and some convention over configuration simplifications for join columns and join tables.
