Refactored EditorManager to consolidate popup drawing methods into a single DrawPopups method and added a DrawMenuBar method. Replaced DrawYazeMenu with DrawHomepage for displaying a welcome message and options for opening a ROM. Introduced a LoadRom method to handle ROM loading and updated related methods to set the current_rom_ pointer. Added settings_editor_ to the list of active editors.
