Subject: [PATCH] Improve Maps (in item frames) performance and bug fixes
Maps used a modified version of rendering to support plugin controlled
imaging on maps. The Craft Map Renderer is much slower than Vanilla,
causing maps in item frames to cause a noticeable hit on server performance.
This updates the map system to not use the Craft system if we detect that no
custom renderers are in use, defaulting to the much simpler Vanilla system.
Additionally, numerous issues to player position tracking on maps has been fixed.
