[v0.11.1] Updated URLs (Quick patch)

Quick patch to update URLs in the in-game prototype message to point to new websites of this game project and its parent project.

[v0.11.0] Renamed parent project, added options screen and more

• options screen and underlying services were finally implemented
• replaced old name of parent project by new one (identifiers/URL/logo)
• package metadata now relies solely on the pyproject.toml file
  • setup.cfg isn't used anymore and was thus removed
• README text and media were improved
  • includes new instructions in the subsection about contributing

[v0.10.0] Several new systems/services

New systems/services like:

• main menu
• title screen
• configurable controls for keyboard and gamepad

We also adopted pygame-ce as the game library in lieu of regular pygame.

Python 3.7 or above is now required to play the game.

We also added the needed backend to support input playing/recording. Such services are mostly functional. They were tested and were working fine before, but now they need a few small changes to take into account recent changes/additions related to the usage of configurable controls for keyboard and gamepad.
