item.fireworksCharge.fadeTo is too bad for some languages

Fireworks Star can customize color to fade out,
and its description string is "Fade to <color>".
In en-US.lang, its entry is 'item.fireworksCharge.fadeTo=Fade to',
there is no chance to change word order.
At least in Japanese, I want to change it.

This entry should be "Fade to %s" (%s will replace color name).
