Subject: [PATCH] Configurable Chunk Inhabited Time

Vanilla stores how long a chunk has been active on a server, and dynamically scales some
aspects of vanilla gameplay to this factor.

For people who want all chunks to be treated equally, you can chose a fixed value.

This allows to fine-tune vanilla gameplay.
