[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.

[2.0] Fix casing bug in Parser - IfFunction checks lower-case the function name, but register methods don't.

[2.0] DDC-163 - Missing DQL Alias prefix for many-to-many table in SqlWalker lead to duplicate prefix generation in SQL statement when a many-to-many join table is used more than once.

[2.0] DDC-214, DDC-303, DDC-304 - Fix several errors with Schema Inference from Database and Metadata and Comparisons, aswell as related bugs in DatabaseDriver. DDC-305 - Abstracted TRUNCATE command for all platforms.

[2.0] Added more configuration options that optionally allow to generate PDepend and PHPMD reports and version them by svn revision

[2.0] Refactoring of build.xml to generate coverage xml optionally via build.properties. Also added option to set the phpunit xml configuration file.

[2.0] DDC-302 - Fix failures occuring from Sqlite Tests in this regard - No test coverage for this features now.

[2.0] Updated Build process to use a new PHPUnit Phing Task and seperate "Common" and "Performance" Tests into different executions, the first one halts on failures the second doesnt.

[2.0] DDC-268 - Exchanged DoctrineException for MappingException and added missing exception method (thanks to Christian Heinrich for the patch)

[2.0] DDC-271 - Add columnDefinition for Join-Column in Annotation, XML and YAML driver, updated SchemaTool to use Join Column definition instead of using the column's columnDefinition if specified. Refactored MappingDriverTest to allow for feature specific test-cases instead of one large assertion block. Fixed typos in XmlDriver - Updated doctrine-mapping.xsd Schema File
