Getting dyld warnings when I run synx in El Capitan

dyld: warning, LC_RPATH @executable_path/../../../../../../../SharedFrameworks in /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/../../..//DVTInstrumentsFoundation.framework/Versions/A/DVTInstrumentsFoundation being ignored in restricted program because of @executable_path
dyld: warning, LC_RPATH @executable_path/../lib in /Applications/Xcode.app/Contents/Frameworks/IDEFoundation.framework/Versions/A/../../../../Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/libclang.dylib being ignored in restricted program because of @executable_path
dyld: warning, LC_RPATH @executable_path/../lib in /Applications/Xcode.app/Contents/Frameworks/IDEFoundation.framework/Versions/A/../../../../Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/libLTO.dylib being ignored in restricted program because of @executable_path
dyld: warning, LC_RPATH @executable_path/../Frameworks in /Applications/Xcode.app/Contents/PlugIns/Xcode3Core.ideplugin/Contents/MacOS/Xcode3Core being ignored in restricted program because of @executable_path

The app still works, it just gives me those warnings before it runs.

These are no longer emitted from Xcodeproj 0.28.2. Can be fixed by #86.
