Matthias Richter 0dc1e6c719 Issue #25: Division by 0 in CircleShape:support(). 
support(A,B, 1,0) returns 0,0 when A and B are touching in a vertex of
both A and B AND this vertex is on the right of A's center (in direction
(1,0)), e.g. this situation:

    .---.
 .-.| B |
: A x---'
 '-'

Then: support(A,B, 1,0) = A:support(1,0) - B:support(-1,0) = x - x = 0

Since CircleShape:support(dx,dy) normalizes dx,dy this will result in a
division by 0 error in the subsequent execution of the GJK algorithm.

An early out with result 'not colliding' (in accordance to the other
edge cases) prevents this error.
