libretro-super/retroarch-release.sh
Nathan Strong 9ce305940b Add a safety check to retroarch-release.sh
== DETAILS
After running this script and inadvertently nuking my fork, I've
added a safety check so that it doesn't happen to anyone else.

Change summary:
- update the .gitignore to ignore wiiu artifacts and Mac OSX junk files
- add two command-line parameters to `retroarch-release.sh`:

  * `--clean` will execute the legacy behavior of deleting and re-
    cloning `libretro/RetroArch`
  * `--force` will execute the release script using the current
    state of `retroarch/` without re-cloning, although it will still
    do a `git pull` and fetch submodules.

  If neither argument is provided, then the script fails with
  instructions if it detects that the `retroarch/` directory already
  exists.
