Fixing an invalid loaded file does not cause the file contents to reappear

[vabold]

Steps to reproduce:

1. Load a valid CSV into the editor
2. With another text editor, edit the CSV to an invalid state (example: change A to 2)
3. Edit the CSV again with the other editor (example: change A to 0)

What will currently happen is that the file will be closed altogether when detecting an invalid change.
Should there be something to improve upon that?

Actually upon review, the following behavior occurs:

• Changing button columns to any value > 1 causes the checkbox to be unchecked
• Changing DPad to any value sets it to that value (even if it's not 0-4)
• File is closed altogether on invalid stick setting.

For now I'll modify the button columns and DPad column to act the same way as the stick.

Behavior is fixed with 5d91402

Leaving this issue open to discuss if we want to change behavior in future.
