More Vector math functions

[Bowserinator]

Some of the Vector3 functions have no Vector2 equivalent and vice-versa, this helps increase parity a bit. Functions added for Vector2 and Vector3:

Vector2 Vector2Min(Vector2 v1, Vector2 v2);
Vector2 Vector2Max(Vector2 v1, Vector2 v2);
Vector2 Vector2Refract(Vector2 v, Vector2 n, float r);
Vector3 Vector3MoveTowards(Vector3 v, Vector3 target, float maxDistance);

Also added Vector4 math functions:

Vector4 Vector4Zero(void);
Vector4 Vector4One(void);
Vector4 Vector4Add(Vector4 v1, Vector4 v2);
Vector4 Vector4Subtract(Vector4 v1, Vector4 v2);
Vector4 Vector4SubtractValue(Vector4 v, float add);
float Vector4Length(Vector4 v);
float Vector4LengthSqr(Vector4 v);
float Vector4DotProduct(Vector4 v1, Vector4 v2);
float Vector4Distance(Vector4 v1, Vector4 v2);
float Vector4DistanceSqr(Vector4 v1, Vector4 v2);
Vector4 Vector4Scale(Vector4 v, float scale);
Vector4 Vector4Multiply(Vector4 v1, Vector4 v2);
Vector4 Vector4Negate(Vector4 v);
Vector4 Vector4Divide(Vector4 v1, Vector4 v2);
Vector4 Vector4Normalize(Vector4 v);
Vector4 Vector4Min(Vector4 v1, Vector4 v2);
Vector4 Vector4Max(Vector4 v1, Vector4 v2);
Vector4 Vector4Lerp(Vector4 v1, Vector4 v2, float amount);
Vector4 Vector4MoveTowards(Vector4 v, Vector4 target, float maxDistance);
Vector4 Vector4Invert(Vector4 v);
int Vector4Equals(Vector4 p, Vector4 q);
