Menus

[mbonig]

The menus aren't really doing much at this point. This should be fixed:

File:

• Open (mostly works from the splash page right now, should allow the user to pick the root of the cdk app or the cdk.out directory)
• Open Recent -> (show last 10 opened)
• Save As -> save currently display as a png. Mimic Lucid's export.
• Close (this should just clear out the zustand state)
• Quit - Should quit and close the app

Edit:

• Undo (this works, doesn't need changes)
• Redo (this works, doesn't need changes)

View:

• Not sure?

Help:

• Link to this Repo
• Eventually links to videos?
