Singularity: Add recipe

[win8linux]

Endgame: Singularity is a game where players become a self-aware artificial intelligence with the goals of covertly taking over the world and achieving technological singularity.

This is a re-do of #5630 after an attempted rebase went horribly wrong there. This PR contains the original commits atop master as of the time of creating this PR.

With the updated texts, this is the output when attempting to run the game from Terminal:

After updating to Python 3.9 the game works now (x86_64):

An icon is ready, however attempting to add it to the binary via the typical method (addResourcesToBinaries) results in making the game non-executable. Otherwise, the game's fine now.
