Add idle-familiar plugin

[mackenzie0cameron0]

The idle familiar plugin is a pop-out, always on-top, widget. It reads a players in-game state and plays a corresponding animation. This is intended to act as an idle notifier while the client is minimized.
It's a status display only: no game input, automation, or interaction with the client. The README has previews and full feature list.

• use of reflection is not allowed

[mackenzie0cameron0]

I've removed the reflection and replaced it with a whitelist of animation IDs. The plugin should still function the same. Thank you for your time in reviewing this.

programmatically manipulating the main game window, such as trying to request focus, minimize, move it, etc. are not allowed

Removed the return-to-game button & added shimmer effect to the collapsed widget for idle status
