AppleSupportDownloadInfoProvider.py breaks with new Support Doc structure

[jazzace]

I started working on a pull request to fix the custom processor to address the recent reorganization of the Apple Support Docs and then realized that there is almost nothing left there to download. You have deprecation warnings on most of your recipes using that processor. Based on the new documentation format, I was able to create an AppleSupportContent.download recipe that replaces the functionality of your custom processor for this new structure. I updated the two products I currently have in my repo to use this new recipe as a parent.

It may be time to simply eliminate all the existing recipes that use AppleSupportDownloadInfoProvider.py in your repo, and if there are one or two that are still relevant, you can use my new recipe replacement. Regardless, my recipes no longer require this processor. Thanks for all the fishes!
