AntiSpeedrun v0.2.0

Added

• config.yml carries a config-version (1). On start and on /asr reload an older file, including the unversioned v0.1.x shape, is migrated forward: missing keys are added with their shipped off defaults, comments are kept, and the old file is saved to backups/ first. The upgrade from the unversioned shape also sets anti-cheese.block-bed-anchor-boss-damage, block-exit-portal-crystal-place and block-gateway-pre-dragon from true to false, once, with a WARNING per key: v0.1.x shipped them true without enforcing them, so false keeps what the server did. Set one back to true to turn it on. No other value is changed. A newer or unreadable version stops startup with the file untouched. State files are not versioned yet.
• anti-cheese.block-bed-anchor-boss-damage, off by default, cancels bed and Respawn Anchor explosion damage to the Ender Dragon (including its parts) and the Wither, detected by DamageType.BAD_RESPAWN_POINT. TNT, arrows and melee are not affected. Its shipped default changes from true to false; it was parsed only until now.
• anti-cheese.block-exit-portal-crystal-place, off by default, refuses an End Crystal placed on the exit portal's centre column. The four resummon ritual positions are not affected. Its shipped default changes from true to false; it was parsed only until now.
• anti-cheese.cap-single-hit-boss-damage, off by default, enforces
  max-single-hit-boss-damage against the Ender Dragon and the Wither. The cap applies to final
  damage after armour and resistance, including hits on the dragon's parts, so stacked TNT
  minecarts and Mace smashes cannot skip the fight.
• Outer-End boundary (anti-cheese.block-gateway-pre-dragon, outer-end-radius, outer-end-poll-seconds) holds players within the radius until the world's first dragon is killed. It is off by default, including in every bundled profile.

Upgrading from 0.1.x

• Every new anti-cheese rule ships off. Enable the ones you want in config.yml under
  anti-cheese, then run /asr reload.
• On first start the config migration adds config-version: 1, saves the old file to
  plugins/AntiSpeedrun/backups/, and switches block-gateway-pre-dragon,
  block-exit-portal-crystal-place and block-bed-anchor-boss-damage from true to
  false, once, because in 0.1.x they did nothing. Set one back to true to enforce it.
• A clean install also works: back up plugins/AntiSpeedrun/ and playerdata, delete
  config.yml, install the jar and restart. Deleting config.yml loses every local edit
  and any preset applied with /asr profile apply; the regenerated file is the default
  SMP_STANDARD. State files carry over.
