Split Cornerstone in to Separate Projects.

One for iOS.
	Cornerstone/project/Cornerstone.xcodeproj/project.pbxproj -> Cornerstone/project/Cornerstone for iOS.xcodeproj/project.pbxproj
	Cornerstone/project/Cornerstone.xcodeproj/project.xcworkspace/contents.xcworkspacedata -> Cornerstone/project/Cornerstone for iOS.xcodeproj/project.xcworkspace/contents.xcworkspacedata
	Cornerstone/project/Cornerstone.xcodeproj/xcshareddata/xcschemes/Cornerstone for iOS (Debug).xcscheme -> Cornerstone/project/Cornerstone for iOS.xcodeproj/xcshareddata/xcschemes/Cornerstone for iOS (Debug).xcscheme
	Cornerstone/project/Cornerstone.xcodeproj/xcshareddata/xcschemes/Cornerstone for iOS (Release).xcscheme -> Cornerstone/project/Cornerstone for iOS.xcodeproj/xcshareddata/xcschemes/Cornerstone for iOS (Release).xcscheme

And one for OS X.
	Cornerstone/project/Cornerstone.xcodeproj/project.pbxproj -> Cornerstone/project/Cornerstone for OS X.xcodeproj/project.pbxproj
	Cornerstone/project/Cornerstone.xcodeproj/project.xcworkspace/contents.xcworkspacedata -> Cornerstone/project/Cornerstone for OS X.xcodeproj/project.xcworkspace/contents.xcworkspacedata
	Cornerstone/project/Cornerstone.xcodeproj/xcshareddata/xcschemes/Cornerstone for OS X (Debug).xcscheme -> Cornerstone/project/Cornerstone for OS X.xcodeproj/xcshareddata/xcschemes/Cornerstone for OS X (Debug).xcscheme
	Cornerstone/project/Cornerstone.xcodeproj/xcshareddata/xcschemes/Cornerstone for OS X (Release).xcscheme -> Cornerstone/project/Cornerstone for OS X.xcodeproj/xcshareddata/xcschemes/Cornerstone for OS X (Release).xcscheme

Add a workspace so we can work on both at once.
	Cornerstone/project/Cornerstone.xcworkspace/contents.xcworkspacedata

Next step, restore sanity to the class and file names.
Use Proper Class and File Naming.

Now that Cornerstone for iOS and OS X are in their own projects we don't need to worry about duplicate file names so we can rename classes and files to something more proper.

Remove ~platform from files that had the same name (and largely the same purpose).
	Cornerstone/source/endpoints/ios/Cornerstone~ios.pch -> Cornerstone/source/endpoints/ios/Cornerstone.pch
	Cornerstone/source/endpoints/osx/Cornerstone~osx.pch -> Cornerstone/source/endpoints/osx/Cornerstone.pch
	Cornerstone/source/endpoints/ios/main~ios.m -> Cornerstone/source/endpoints/ios/main.m
	Cornerstone/source/endpoints/osx/main~osx.m -> Cornerstone/source/endpoints/osx/main.m
	Cornerstone/resources/ios/Cornerstone-Info~ios.plist -> Cornerstone/resources/ios/Cornerstone-Info.plist
	Cornerstone/resources/osx/Cornerstone-Info~osx.plist -> Cornerstone/resources/osx/Cornerstone-Info.plist

Use standard class naming instead of trying to infuse the platform name.
	Cornerstone/source/endpoints/ios/CIApplicationDelegate.h -> Cornerstone/source/endpoints/ios/CSApplicationDelegate.h
	Cornerstone/source/endpoints/ios/CIApplicationDelegate.m -> Cornerstone/source/endpoints/ios/CSApplicationDelegate.m
	Cornerstone/source/endpoints/osx/COApplicationDelegate.h -> Cornerstone/source/endpoints/osx/CSApplicationDelegate.h
	Cornerstone/source/endpoints/osx/COApplicationDelegate.m -> Cornerstone/source/endpoints/osx/CSApplicationDelegate.m

Update references to files and classes that were renamed.
	Cornerstone/project/Cornerstone for OS X.xcodeproj/project.pbxproj
	Cornerstone/project/Cornerstone for iOS.xcodeproj/project.pbxproj
	Cornerstone/project/xcconfig/cornerstone__ios.xcconfig
	Cornerstone/project/xcconfig/cornerstone__osx.xcconfig
	Cornerstone/resources/osx/en.lproj/MainMenu.xib
