NSUndoCloseGroupingRunLoopOrdering enum. Replace instance
variables _registeredUndo with _runLoopGroupingPending and
_actionName with _unused1.
* Source/NSUndoManager.m: Added documentation.
Added actionName instance variable to PrivateUndoGroup.
(-[PrivateUndoGroup actionName]): New method.
(-[PrivateUndoGroup setActionName]): Ditto.
(-[PrivateUndoGroup dealloc]): Release new instance variable.
(-[PrivateUndoGroup initWithParent:]): Initialize actionName.
(-[NSUndoManager forwardInvocation]): Implicitly call
beginUndoGrouping if group has not been setup and we are
grouping by events. Register _loop: invocation if none is already
pending and if we are grouping by event.
(-[NSUndoManager registerUndoWithTarget:selector:object]):
Ditto.
(-[NSUndoManager methodSignatureForSelector:]): Overriden to
forward request to target supplied by
-prepareWithInvocationTarget: if available.
(-[NSUndoManager _loop:]): Set flag to determine pending
_loop: processing.
(-[NSUndoManager init]): Removed access to _actionName. Have
receiver default to group by event.
(-[NSUndoManager dealloc]): Ditto.
(-[NSUndoManager enableUndoRegistration]): Remove access to
_registeredUndo.
(-[NSUndoManager redo]): Simplified implementation.
(-[NSUndoManager redoActionName:]: Retrieve action name from
first grouping of the redo stack.
(-[NSUndoManager redoMenuTitleForUndoActionName:]): Add
comment about localization.
(-[NSUndoManager undoMenuTitleForUndoActionName:]): Ditto.
(-[NSUndoManager setActionName:]): Forward call to current
grouping.
(-[NSUndoManager undoActionName:]: Retrieve action name from
first grouping of the undo stack.
(-[NSUndoManager setRunLoopModes:]): Use correct run loop
ordering and set flag for pending _loop: invocation.
(-[NSUndoManager undoNestedGroup]): Removed special case
handling of _registeredUndo. Raise
NSInternalInconsistencyException if grouping is still in
progress. Simplified implementation.
