A few small UX issues.

1. When creating a new mod in the dev tab(rc10), entering anything in the name tab will wipe out anything in the ID field, even if you've already entered an ID. This is surprising and unwelcome behavior, my expectation would be for it to retain anything I'd explicitly entered
2. When entering a name, special characters that are perfectly allowed elsewhere are not allowed in the initial name entry field.
3. Spaces in the name field are merely omitted, rather the more customary underscore.
