0.11.0

Breaking

• Added support for Xcode 5.
• The ARCHS option is not set anymore and will use Xcode’s defaults. This
  fixes the build and archive issue with the new arm64 architecture.
  CocoaPods#1352
• The default of the ONLY_ACTIVE_ARCH setting has changed to YES
  in the Debug configuration. This means that if this is a static library,
  the application that links the library in will have to make the same
  adjustment, or the build will fail.
• [Project] #add_system_framework has been removed in favor of
  PBXNativeTarget#add_system_framework.

Enhancements

• [Command] Added new subcommand sort, to sort projects from the command
  line. This command is useful for sorting projects as well to easy comparison
  of existing projects.
• [Project::Object] Added #sort.
• [Project] Added #sort, #add_system_library.
• [Project::ObjectList] Added #move and #move_from.
• [PBXNativeTarget] Improve #add_dependency to avoid duplicates.
• [PBXNativeTarget] Added #add_system_framework, #add_system_frameworks,
  #add_system_library, #add_system_libraries.
• [PBXFileReference, PBXGroup] Added set_source_tree and #set_path.
• [PBXGroup] Added find_file_by_path.
• [AbstractBuildPhase] Added #file_display_names, #build_file, and #include.

Bug Fixes

• [Command] Fixed opening existing projects.
• [GroupableHelper] Improved handling of ambiguous parents.
• Decode XML entities in project paths when reading workspace files. This
  prevents double-encoding the entities (for example, ') when writing
  the file.
  amolloy
• Fix C-ext memory leak by closing and releasing the CFWriteStream used to write
  projects when done.
