[BUG] Console Key Keybinder confirmation prompt Yes / No buttons function reversed

[levicki]

Steps to reproduce:

1. Open Console Key Keybinder
2. Click on Change full key or Change mini key button for an installed game which has no backup, you will get this prompt

Expected behavior:

• Clicking Yes should allow you to change the key binding

Actual behavior:

• Clicking Yes does nothing, while clicking No allows you to change key binding

While we are at it, it would be nice if each key could be cleared (unassigned). If it is already possible it is not immediately obviousl.
