replaced calls to 'UI_USER_INTERFACE_IDIOM()'

This macro was provided vor iOS 3.2; Sparrow 2.0 requires iOS 5, so it's no longer necessary.
added blocks to delayed invocation (and juggler)
removed the 'forTouch:' argument of the 'hitTestPoint:' method

I don't think it was *ever* called with 'forTouch:NO' ;-)
