Updates the SnapAndRun iPhone app so that it builds with Xcode 4.

This essentially changes the libObjectiveFlickr.a target to use only the
current iOS SDK -- no longer a Mac project. This doesn't affect the
ObjectiveFlickr.framework target, which is still a Mac project.

Also, SnapAndrun now uses the current iOS SDK, instead of fixing on iOS 4 SDK.
