Regenerated Xcode projects.

Updated the Xcode projects to include wakeuppipe.cpp.
Also fixes the wxiphone project which appeared to have 2 source file references concatenated (stattext.mm and slider.mm) since the last commit. This unfortunately happens sometimes when running makeprojects.applescript.
