Changed loadModels() once again. Removed loading of models based solely on model filename. Added support for different models with the same file names. All models files are required, in order to determine class names. The changes result in an overall increase in flexibility with respect to model file names.

Introduced a new attribute ATTR_AUTOLOAD_TABLE_CLASSES that can be used to control whether Doctrine should try to autoload custom table class files when looking for them.

Consolidated a few things. Initial entry of Inflector class. Moved some methods from Doctrine base class to Doctrine_Lib and Doctrine_Inflector.

Added isValidModelClass() static method and fixed getLoadedModels() in order to resort back to the (classical) approach of class inclusion as a fallback when record classes have different names than their file names. The fallback behaviour of getLoadedModels() is now similar to what is was before the changes introduced in rev 3002.

Added to autoloading to support caching the loaded model paths so we can retrieve them with autoload.

Moved static methods from Doctrine class to Doctrine_Facade and updated the tasks to use Doctrine_Facade.
