Elements: Nexus

Elements: Nexus 1.0.4

• /nexus reload now reloads everything except the features.toml on/off switches and the storage type: all config files and every data file in the store (holograms, kits, warps, spawn, ranks, players, homes and the rest)
• Data files edited by hand are read as saved; other data files save their in-game changes first; a file that can't be read keeps what was loaded and is named in the reply
• Holograms respawn from the reloaded data, ranks and nicknames apply to online players right away, and jail status is matched to the reloaded data
• Discord bot reconnects on reload only when the token, server or channels changed
• Dragon respawn is configurable in dragon.toml: portal mode (auto, vanilla, fixed), crystal placement (bedrock, offset, list), misplaced crystal cleanup, player radius, retries, staff alert and fix_portal_location
• Dragon respawn now starts with the crystals Nexus places, and detects a respawn already in progress
• Added /nexus dragon status, respawn and spots
• Added /holo move and /holo createat, both usable from the console
• /rank group perm value-node examples are now generic
• Version 1.0.4; CHANGELOG, README and SPEC updated
