Support Humble Games Launcher installs!

[27hectormanuel]

Support the beta launcher subscription games

[UncleGoogle]

research done:

• there is nice URI protocol to install/launch games humble://<cmd>/<machine_name>
• I've installed one game (Forager) from "By Humble Games" and looks it has no DRM so I can skip Humble Launcher this way and run it directly (may be important for #170)
• there is one big config file at %appdata%/Humble App/config.json to read all games with states and even download progress (if Galaxy ever supports it)
  • there is even lastPlayed timestamp so "Played Recently" in Galaxy for games run by launcher will be visible
  • "user"/"user_key" - app oauth client token?

Now released in 0.11.0!

Please share your feadback if it works for you.

Note on last_time usage: looks like Galaxy ignores "last played" timestamp returned to game keys corresponding to subscription game. What a pity.

@27hectormanuel let me know if you would like to see native support for launching games from humble app -- for now most of them seems to be drm-free, so it would be possible to for example attach double-click on Play button to launch directly (and having it visible in "Recently Played")
