Wind mechanic

The wind is a game mechanic. Eventually when playing a game, wind will appear, and it make some changes in towers and bloons.

Effects
There are 4 categoryes to winds: Normal (nothing happens), Slow (some white lines on the screen), Fast (white and gray lines running in the screen), and Tornado (rocks, leaves and ground on the screen (ground if on a land map, sand if on a sand map, and water if on a water map)).

The wind will blow in a random direction, making different affects deppending on the position of the bloon/tower.

Note: A wind will have same effect than weaker winds (example: fast wind will have theslow wind properties, no only the meant properties).

For towers
Normal: No changes.

Slow: Projectiles will move 1.2x it speed if going at the same wind direction, 0.8x if going opposite to the wind's direction.

Fast: Towers will attack at half speed if attacking opposite to the wind, and will attack 2x faster if attacking at the wind direction.

Tornado: Blow towers in the wind direction.

For bloons
Normal: No changes.

Slow: Bloons will move 1.2x it normal speed if going at the same wind direction, 0.8x if going opposite to the wind's direction.

Fast: Bloons attack projectiles will move 2x faster if in the wind direction, 2x slower if moving against the wind.

Tornado: Sometimes blow bloons in the wind direction, making them return or skip a little of the track.
