Update default for pickNextWaypointDist in AI Path Script

I was just getting started with this project and it seems awesome so far! I ran into an issue that tripped me up for a bit while working with a 2D project, and realized that the documentation for the pickNextWaypointDist in the AI Path script is awesome, but the default is 2.0, which the documentation itself says is “too high”. A default of 1 for this might be more reasonable to avoid newcomers getting stumped on this.


The actual value which is reasonable depends on the scene and game. 2.0 might be a reasonable value in some games, but in other games it might be too high or too low. In the documentation an example scene is shown.
