.hit

These give the bots a sense of touch, allowing them to tell when something has hit them or if they have hit something.

A good use of these are with Blind bots to give them some sense of what is going on around them.

• hit - Has your bot been hit by another bot? Note: doesn't reset to zero.

• hitup - hit from the front?
• hitdn - hit from the back?
• hitdx - hit on the right?
• hitsx - hit on the left?

Note from the C++ front lines

In the 2.4 C++ port (probably will be called 2.5 I think) hitup, hitdn, hitsx, and hitdx will probably be replaced by hitang, which will return the angle of the hit relative to the eye.

The reasons are two fold: hitang would be more useful in practice, and free up 3 other sysvars (making the sysvars file less cluttered).
