Avoid ambiguity (#5809)

* Avoid ambiguity

When you see 'boost: 150%'
It can be 'increase the speed to 150%' or 'increase the speed to 250%'.
Maybe you will say that the colon has already avoided this ambiguity.
But you know there's always someone who ignores those things, and also translating 'boost' is hard with no 'x' to avoid ambiguity.
With a 'x', it will show 'Boost: x150%', which will never be thought as 250%.

* Update OverdriveProjector.java

When power is low, show 'low power: -{0}%';
When power is high, show 'boost: +{0}%'.

Necessary, because the previous one is strange.
2.5 does not make sense. 12.5 does.
