1364 install resource bundles

Closes #1366

Prevent creation of multiple Resource Bundle targets with the same name

Rework resource bundle target creation so that a single common resource bundle target is shared by all targets. fixes #1338

Use `BUILT_PRODUCTS_DIR` instead of `TARGET_BUILD_DIR` so that Copy Resources script succeeds during Archive builds

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.

Closes CocoaPods/CocoaPods#1309

Fix "cannot overwrite directory" when copying OS X frameworks into the resources dir
