Waystones

- Fixed crash when deleting a waystone
- Fixed warp requirements being consumed twice
- Fixed mounts and passengers not teleporting correctly
- Fixed invalid warp requirements resulting in buttons staying disabled with no visible reason
  - They will now show a fallback error pointing out the issue
- Fixed Fleeting Memorial so that it does not require xp
  - If you have not made changes to your `warpRequirements`, it should update automatically
  - If you are using custom `warpRequirements`, either reset them to the default and re-apply your changes,
  - ... or manually replace the `$uses_xp #= ... ` line with `"$uses_xp #= and(any(source(is_waystone), source(is_warp_stone)), not(target(is_fleeting_memorial)))",`
- Fixed waystone Shogi rules not using Waystones' rule scope
  - If you were using a `shogi.rules.json` file for Waystones, it must now be renamed to `waystones.rules.json`
- Fixed effect naming conflict; `is_player` is now renamed to `is_twinbound` to not conflict with `shogi:is_player`
