Update 5-20-17

-Added Left/Right Wall Detectors. Due to some potential collision errors involving Slope Detect, Wall Detectors were added to help prevent the mask from reading a Left/Right Collision in tight spaces. You can use the "Offset" values in each detector to re-position the detectors.

-Added "Enable Detector Check" to the Engine Widget. When enabled, Mask Collisions will not be registered unless the corresponding detector is already overlapping the obstacle. Disabling will use the original system of only relying on the mask collision.

-Removed adding towards Y Position during the XSpeed loop, as it was no longer needed to correct slopes.
