Core Ecosystem (Infection Mod)

Added:
  - The Msg Reader, in the Message Capsule beside the note and the Core Locator (no recipe yet). Sneak and use it: a log of the notes you carry, a compass bar to the Core Tree, the Phasometer's dial.
  - A crashed alien ship, half buried 400 to 900 blocks from the first Core Tree. Its console gives each player a log; within 1500 blocks it is a dot on the reader's bar.
  - The graft arm: from Phase 3 the Core grafts its Gardeners' right arm, one at a time (100 biomass). A grafted Gardener digs 1.5x as fast, hits for 4 and has 16 health.
  - Guard parties of 3 (2 Brute Guards, 1 Scout Guard) or 5 (3 and 2). A party patrols behind its Scout Guard and answers a breach together.
  - From Phase 6, Gardeners bridge rivers up to 6 blocks wide with Infested Ground instead of swimming. A bridge nobody uses comes down after a minute.
  - When the flower's eye first opens, players who can see the stalk have their view drawn to it for 3 seconds.

Removed:
  - Climbing the stalk. The setting stalk_climbable brings it back.
  - The old player-marking code, switched off since early October. Nothing in play changes.

Tweaked:
  - The whole plant bends: a fat stalk rises straight, then one smooth curve hangs the head far out. It swings round to whoever it looks at, the turn running up the stem like a wave; dead, it sags.
  - The flower is alive: alone, it hangs its face low and searches. It breathes, sways and blinks; close up it leans in at you and bristles.
  - The Core Detector is now the Core Locator, a ribbed handheld with a green arrow on its screen. Old worlds keep theirs.
  - /coreco status works at any distance and says how far away the Core Tree is.
  - A Core Tree placed by hand works in the Nether and the End. The meteor still lands only in the Overworld.
  - A player's arrow hurts the Seedpod Launcher (a setting turns it off).
  - Units fell a 2x2 tree trunk whole instead of leaving three columns standing.
  - Lava touching the colony's veins past its claimed land is covered.
  - The Wrapping Vines move like a snake in worm mode and lie still when they stop.
  - The Fossil Core's book is two pages, only what its writers saw.
  - The CurseForge page and the README rewritten for Core Ecosystem.
