Offer to init file rather than "Error: Not enough bytes"?

Muscle memory has me creating files via the explorer then "initializing" them using the editor. This doesn't work with luna, perhaps a button here that would somehow fill in the appropriate contents, following the "Luna: New Image" flow?

I worry about accidental data loss if we offer a button, but we could just initialize an empty image when opening a file containing 0 bytes.
