MacOS Build : 'build.xcode' folder is not an Xcode package - should be renamed

The build prep command "make -f Makefile.osx xcode" places the MacOS build scripts into a folder named build.xcode. However, the ".xcode" extension is recognized by Xcode.app as a build settings file and this folder is not cannot be navigated in the Finder (it shows up as an Xcode package, which it is opaque).

Suggestion is to rename the 'build.xcode' folder to something that does not use a reserved extension so that this folder can be navigated more easily.

WORKAROUND: rename the folder, or use terminal to open build.xcode/mscore.xcodeproj
