#3 Stance detection changes

With the new grinds and new animations the old way of detecting stances is not sufficient. Now I have removed the check stance calls while in air and while in grind.

Fix grind out direction to only use STANCE will make it temporarily more playable.

I want to leave stance changing while in air off.

Need to write new stance detection that takes into account playing animation and changes stance AND animation appropriately.

Need to add animations for changing stances while on ground: roll manual

While grinding: all 5050 type grinds leave boardslides alone until transition side is implemented?

changes here broke grindout direction using stance. need to implement anim changes if stance changes while grinding. 90c3229274

doing manuals should be high priority now.

boardslide grinds are next priority here.

this is mostly done. will break out grind issues separately.
