Add `--copy-links` argument to rsync invocation during Resource Bundle copying. refs CocoaPods/CocoaPods#1309

This ensures that destination files are copied into the application bundle instead of symbolic links preventing the creation of invalid apps during Archive.
Use `BUILT_PRODUCTS_DIR` instead of `TARGET_BUILD_DIR` so that Copy Resources script succeeds during Archive builds
Add CHANGELOG entry detailing Resource Bundle fixes. refs #1329
