Tailwind not a field feature

[jmoonie]

Knowing a Pokémon’s speed tiers is one of the most crucial things in VGC. One of the moves which affects speed is tailwind (essentially doubling speed for all Pokémon on your side of the field). The fact that there is a helping hand field effect but no tailwind effect makes it difficult to determine if your side can outspeed the opponent.

Ask: Implement a Tailwind widget that when clicked will show the Pokémon’s speed after tailwind, and when turned off returns the speed to its original value.
