Shapes should be extracted into a separate library

[haykam821]

The shapes system allows for powerful definitions of a map's dynamically-generated layout. Having this system available to other minigames through a shared library would reduce duplicate code needed to extend map configurability.

In addition, shapes could be shared across multiple game configurations of different game types, particularly through use of a dynamic registry; for example, a nucleoid:tater shape could define a pattern without needlessly repeating this pattern across multiple configurations.
