0.6.0

NOTE: This release changes the way that the rules_apple dependencies should be loaded. Please note the change in the README regarding how to structure your WORKSPACE file.

• Applications and other bundles can now depend on swift_library targets that use the new bazelbuild/rules_swift rules.
  • You may not, however, mix rules_apple swift_library and rules_swift swift_library in the same dependency tree. You must migrate your entire application in order for it to work correctly.
• macos_command_line_application: Added a launchdplists attribute that merges a list of .plist files and embeds them into the binary in the __TEXT, __launchd_plist section.
• Add support for deduplicating resources from the test bundle that are also present in the test host.
• Only process plist and strings files for builds using --compilation_mode=opt.
• Fix the -add_ast_path flag passed by Swift to the linker so that .swiftmodule files are actually embedded in the binary.
• General code cleanup.
