Usercript for SteamGifts.

Adds Linux compatibility info from ProtonDB to games in giveaways on SteamGifts (near comments and entries counters on the home page and above remaining time on the giveaway page).

Show overall game tier (Linux compatibility/playability state of the game) for each giveaway. In the tooltip (shown on mouseover) it also shows the recent tier based on recent reports (with new Proton versions) and the count of reports for the game.

To reduce the count of requests to the Steam and ProtonDB servers (and prevent blocking/blacklisting on those servers) script limits requests to 3 per second and caches results in Tampermonkey storage. After caching games info script will automatically update the cache after 1 week (on demand when game will be on giveaway, so it can be more than week) to have actual info.
