Add Discord Rich Presence Abstraction

[QueenOfSquiggles]

Is your feature request related to a problem? Please describe.
No problem. Enhancement

Describe the solution you'd like
I would like the framework to include an autoload that can read some minimal data from the configuration file and create a discord rich presence.

Describe alternatives you've considered
Nope. Enhancements!

Are you prepared to write the solution to this feature? If so please describe how you intend to implement it
Hell yeah! I already made a basic test.

Additional context
Documentation for the nuget package that enables this is here:
https://lachee.github.io/discord-rpc-csharp/#discord-rich-presence

Also note that you have to make a discord app registered on their website to have assets uploaded.
Use the developers/applications page for managing this!

Note, I might have to wait until after Ludum Dare to implement this. Which may actually give me a chance to test out the rich presence API (at the current moment I have not successfully gotten the image assets to work)

Working on this now as a stress test for #81
