In the generated/simulated events output by touch exploration controller,
there's only one finger down, right? If so, "All fingers" doesn't sound right

[evy, 2014/06/16 20:34:20]

In this test, that's true - so I'll change it.
I was thinking about the case when extra fingers are added - but we didn't
actually test this, and there are still bugs in that case so I'll be adding
tests specific to checking all fingers released in a bit.
