Enhancement: Option to Audit Games Owned On Store

[Quinn]

Demos and the like are included in the games imported when importing Steam games, but I don’t see anything in Launchbox to easily remove games if they are removed from a Steam account. I don’t know if Launchbox “sees” games that are only on the account temporarily due to free weekends or the like, so those might or might not be relevant.

It would be useful to be able to do the same kind of scan that is used to detect new Steam games on the account, but the other way around- detecting games that are listed as launchable via Steam, but are not on the linked account. Could output in a similar way to importing games, or the way the Audit works, since it is unlikely a large number of games will be removed. It should be pretty easy to delete them by hand if the user wants to.
