Sensors do not create contacts, or fire contact listeners.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a ContactListener on your world, with BeginContact defined to log 
it's use
2. Create a dynamic body with a fixture of some sort attached
3. Create a static body with a sensor fixture attached
4. Drop dynamic body on to sensor
5. observe BeginContact on ContactListener does not fire

What is the expected output? What do you see instead?
I expected BeginContact to fire, and this didn't happen. I also expected the 
sensor object's ContactList to contain contacts referencing the objects within 
it. This was also not the case.

What version of the product are you using? On what operating system?
2.1a.1, in Google Chrome (current, stable channel).

I think b2Shape.TestOverlap isn't working right, when fed a thing and a sensor?

Can you please provide a test case?
I don't see any problems using BeginContact.

I attached my test case. Note that it depends on a littler test-helper-script 
(b2t object).
