Subject: [PATCH] Do crystal-portal proximity check before entity lookup
This adds a very cheap distance check when an end crystal is placed.
Attempting to respawn the dragon, which involves looking up the end crystal
entities near the portal, every time an end crystal is placed, can be slow on
some servers that have players placing end crystals as a style of combat.
The very cheap distance check prevents running the entity lookup every time.
