Add game library management options

[MayeulC]

A few useful features would be to:

• Add an interactive mode (not sure what counts as interactive, but extend the command line)
• Allow listing games, books, and other media
  • Allow listing games, books, and audio
  • Allow listing bundles and purchases
• Allow downloading individual media, or categories
  • Allow downloading categories
  • Allow downloading individual games, ebooks or others based on their machine name
  • Allow downloading individual bundles or purchases based on their machine name or the key
• Allow listing steam keys, and exporting them
• Compare steam keys with games registered in an account to show unredeemed ones

I have a few more ideas down the line with what we could do with that... :)

+1 to this feature too, HB is not doing this job very well, and data of owned games can be public to work with.

Maybe this style of interactive downloading can be used

I've been wondering about managing older versions of games as well. Personally, I only want to keep the newest version, so I hacked together a little script to detect older files and delete them. The disadvantage to that plan is that sometimes things actually get removed from the HB library (like a linux version gets pulled for some reason). Does anyone else have interest in deleting older verions of games?
