REVIEWED: `Vector2Angle()`

patrix=>matrix

* Fix vector2angle

* Fix ;

* use acosf

* need a break

* add comments

With this fix the function still returns negative values, which is
wrong. But we keep this behaviour to maintain backwards compatibility.

* Fix raymath warning with floor to floorf

* signed unsigned missmatches

* add wrap function

* fixed Wrap function wrapping wrong

This reverts commit 81157e4e72.

* Augment raymath.h with useful functions

* Rename Vector2ClampMagnitude and Vector3ClampMagnitude to Vector2ClampValue and Vector3ClampValue

* Remove Vector3{Up,Down,Left,Right,Forward,Backward}

* Fixed functions Vector2Angle and Vector3Angle

* typo

* Unrolled everything.

Following the pattern in Vector3Normalize.

functions use radians, making this awkward to use.
