VAB angle snap toggling hotkey does not save remapping

[adamzl]

If you re-assign the "Toggle Angle Snap" hotkey it does not save across restarts of the game.

Reproduction:

1. Change the "Toggle Angle Snap" hotkey to Z.
2. Restart the game
3. Observe in the VAB that the C key remains in effect for toggling.
4. Go back to keybinds, note the key is listed as Z, "Apply Settings"
5. Keybind is fixed until next restart.

It happens to all key bindings. When you launch the game, you have to open the key binding interface and update a binding in order for the key binding to be load to what you saved.
