Fixed a typo in a UI string.

Added an option to the pause menu(bottom of screen) that allows you to reset the mod bindings for the currently loaded save game. You will need to save the game again before these changes are persisted into the save game. This should let you get rid of the constant asking for confirmation on loading a save game if you have determined that it is safe to load the save anyways.

Fixed the preview picture because the mod tool doesn't copy the preview image file over when you build the project after the first time.
