v1.2 - New rule, general improvements

Added a new rule. Not the hardest but it definitely has potential to be confusing. Excellent! Again, the spoiler rule list has been updated with it.

Added another shape.

Changed all of the text in the game to be generated on scene startup rather than all the letters being manually placed. This wasn’t required but it will make my life easier for future updates, and it also makes the scenes less cluttered in the editor. Also changed the splash text to reflect my rebranding (had to happen eventually!)

Eliminated all the annoying engine warnings regarding signals - easy fix. I don’t know why I didn’t do this earlier.
