Advanced platformer movements

Let platformer characters: air jump, wall jump wall sliding, coyote time and dashing.

Authors and contributors to this experimental extension: D8H, shadow00dev, Entropy, CorianderGames.

This extension provides behaviors to:

Jump in mid-air
Jump and slide against walls
Dash horizontally
Dash toward the floor
Do coyote time, also known as "ledge tolerance". It lets players jumping even after their character is no longer touching the ground for a given amount of time. It aims to give players a feeling of control and reduce frustration.

An example allows to check it out (open the project online).
