API CHANGE Removed File->resetFilename(), use File->updateFilesystem() to update the filesystem, and File->getRelativePath() to just update the "Filename" property without any filesystem changes (emulating the old $renamePhysicalFile method argument in resetFilename()) API CHANGE Removed File->autosetFilename(), please set the "Filename" property via File->getRelativePath() MINOR Added unit tests to FileTest and FolderTest (some of them copied from FileTest, to test Folder behaviour separately) ENHANCEMENT Added File::$allowed_extensions (backport from 2.4 to enable File->validate() security fix) git-svn-id: svn://svn.silverstripe.com/silverstripe/open/modules/sapphire/branches/2.3@108062 467b73ca-7a2a-4603-9d3b-597d59a354a9
