Update schemes to only allow run. Now it is possible to build/run/debug mobileExecutable as well as desktop from within Xcode. Xcode demands that the path to the debug executable it not relative, this of course gives a portability problem. The path selected are ~/develop/src/subsurface/build.... to at least give it a shine of not being fixed. Signed-off-by: Jan Iversen <jani@apache.org>
