- Packaging and archiving for modern IOS/Mac:

- When doing standard BuildCookRun, package will simply finalize the (likely already finalize) .app in Binaries/<platform>
  - When using Distribution mode, packge will create a .xcarchive in the Xcode Library (as seen in Organizer) to be able to distribute in various modes
  - Archiving will copy either the .app or .xcarchive made above to the archive directory (it will always copy the most recent .xcarchive, since we don't create the directory name, we can't know which archive to copy, so the most recent one wins - not an issue when using -package, because it always makes a new .xcarchive)
- A few code cleanup/refactors in related
