API CHANGE: Simplified state handling so that it's just a key store. Affectors are replaced with GridField_ActionProviders. API CHANGE: Removed GridField state manipulation actions instead opting for GridField_ActionProvider actions.
API CHANGE: Removed support for modifiers that add "body" rows, instead having core support for generating the body rows hardcoded into the GridField.
API CHANGE: Allow modification of columns across the whole GridField with the GridField_ColumnProvider interface.
API CHANGE: Renamed GridField_AlterAction to GridField_Action, and added actionName/args parameters, since it can be used for all actions (including batch actions and row actions)
API CHANGE: Removed GridFieldRow class.
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) (from r107273)

BUGFIX Fixed Folder::findOrMake() not to create "new-folder" through File->setName() if using a trailing slash in the path (which causes an empty name). Added FolderTest to verify this. (from r101266)
