No need for NME for tests, because we don't use anything from flash anymore.
Get rid of async tests, because they fail hard on truly async platforms (neko, cpp). Use very stupid synchronous ShouldCallHelper instead.
Now tests pass on C++ and Neko.
engine.updating can't be changed from outside.
nothing :)
Fix signal removing in js and neko. Switch to using list iterating on js, because otherwise, JS can't check for instance method in a hash (because it calls $bind every time we want to get a method reference and the only way to compare it is via Reflect.compareMethods).
Update for new release.
