Subject: [PATCH] Make interaction leniency distance configurable

The server validates incoming interaction packets by ensuring the player
sending them is inside their interaction range. For this, the server adds
a magic value, by default 1.0, to the original interaction range to
account for latency issues.

This value however may be too low in high latency environments.
The patch exposes a new configuration option to configure said value.
