The key.keyboard.world key codes display incorrectly

Both key.keyboard.world.1 and key.keyboard.world.2 are displayed incorrectly in the key binds screen. They no longer use their translation strings.

key.keyboard.world.1 displays as \ when it should display as World 1.
key.keyboard.world.2 displays as # when it should display as World 2.

Steps to reproduce:

1. Edit options.txt and set a key bind to either world key (or find a keyboard with these keys)

2. Open up the key binds screen and find what you bound those keys to

3. Notice how it displays as \ or # instead of World 1 and World 2
