Making good progress

Today I tackled a little rewrite of the entity definition system, and again received a decent performance and maintability boost. Also added is the ability to export and import 1-to-many entity definitions in archive files that can be reused across multiple world projects. The only thing left aside from scripting (near the end) and a bit more work to the renderer, is to connect the model caching engine to the entity system. Then I can safely say that the entity component of Nexus World Builder is complete.
