Player should keep direction when horizontal speed is zero

[ForNeVeR]

Consider that a player has an ability to turn. For easier reproduction, here's a patch that allows this from the start:

 and OxygenStorage = {

Now, the player presses keys Left, Right.

In the original, this leads to horizontal speed of zero but still left-turning position,

In O21 currently, it leads to right-turning position (the default one).

It should keep the player sprite to face left.
