Added a menubar for workflow management (Save/Load/Close), as well as an About section for credits, updating, and finding the Gitea project on the Bunny Lab Gitea repository. Added automatic workflow centering when you load a workflow, so it spawns the loaded JSON nodes in the center instead of off-screen somewhere at the exact original coordinates. Changed the context menu and hyperlink colors to a more muted blue color
