Fix Xcode 5.0.1 permanent crash on launch

After trying to open a wrong dir (why is it allowed), Xcode 5.0.1 keeps crashing on launch (even directly opening a correct project).

Simply remove this autosave corrupted XCode workspace:

rm -rf ~/Library/Autosave\ Information/Unsaved\ Xcode\ Document.xcworkspace/

And you should be back on track.
