[Irrelevant for Scratch3] SPD: check direction before point in direction

Description

IMPORTANT INFO... This is no longer relevant for Scratch 3. (Also, Scratch 3 breaks the Timer block anyway, so times make no sense.) ====================================== MORE SPEEDTESTS: http://scratch.mit.edu/studios/795672/ ------- This is a simple change from the original project, just testing "point in direction" rather than "switch costume". It shows that Scratch also wastes time pointing in a direction unnecessarily - you should check first, and not bother setting direction if you're already pointing that way! (Unless you know the direction will always be different, of course.) (Yes, when you use the check, it's so fast that all 300 clones often do it before the timer gets a chance to move from zero...) Note that if you also have effects applied when you set direction unnecessarily, then it's even worse - I've actually been kind in not making your browser grind to a halt...
