* Added support for configuration of an arbitrary number of commons-style file repositories. * Split Image.php into filerepo/File.php and filerepo/LocalFile.php * Renamed Image::getImagePath() to File::getPath() * Added initial support for timestamp-based file fetching (OldLocalFile), to be expanded upon by aaron. * Changed the interface for Image/File object creation: use wfFindFile() or wfLocalFile() depending on semantics * ImageGallery::add() now accepts a title object as the first parameter * Moved file handling operations on upload from SpecialUpload to File * Removed path-related functions from ImageFunctions.php. Removed static path accessors from File. * Added a Content-Disposition header to thumb.php output * Improved thumb.php error handling * Updated the unit test suite to kind of partially work with modern computers. RunTests.php doesn't work just yet. Fixed an actual regression that the test suite detected -- moved some defines to Defines.php where they will be loaded consistently.
