Changed init methods.

I changed the init methods in the view controllers for the Mac project. I was getting compiler warnings when I build the project, so I changed the initWithNibName:bundle: methods to call super, and the init method now calls [self initWithNibName:bundle:]. This fixes the compiler warnings, and the app compiles and runs without any warnings or errors.
Doesn't seems to be a good thing to commit. Because other developers will use theirs apple ids and theirs provision profiles which have different identifiers. So I suppose it will require everyone else to manually change it in Xcode before running on a device. Better to allow Xcode to pick appropriate provision profile itself. No need in explicit provision profile IMO...
