Ugly 'fix' for the controller unit test on the p5 bot: in
fail_unless_equals_float() check whether the values are 'almost
equal' by allowing a small absolute error, which should be good
enough for our use cases (normal numbers and values close to 0).
Proper fixage left to floating point arithmetic aficionados.
