* the TxnMgr is invoked by the editor via nsRepository * editor.h|cpp have been renamed nsEditor.h|cpp for consistency * editorInterfaces.h|cpp have been renamed nsEditorEventListeners.c|hpp * added nsITextEditor.h, nsTextEditor.h|cpp. The text editor is a placeholder for the rules unique to text editing. It invokes the nsIEditor to do core editing operations. * reworked nsIEditor and related interfaces as per emerging design. * nsEditor::BeginTransaction and EndTransaction call nsTransactionManager::BeginBatch and EndBatch. git-svn-id: svn://10.0.0.236/trunk@20562 18797224-902f-48f8-a5cc-f745e15eee43
