Hycon - Rcon panel

## Hycon 0.1.26 (changes since 0.1.7)

### Added
- **Chat tab** (moderators and up): everything players said in the last 14 days. Search by word or name, page back with Older, and click a name to open the profile.
- **Chat history** on every player profile.

### Added for Hycon - AntiCheat (needs the AntiCheat addon)
- **Replays (AntiCheat only)**: watch a flagged fight again, with where each player looks and every hit. Play, pause, slow motion (0.5x, 0.25x) and a time slider.
- **3D replays (AntiCheat only)**: blocky players walk over the real world in 3D, with name tags and hit arrows labelled with their distance. Drag to turn, scroll to zoom, Reset camera, or switch to the flat map view.
- **Real world in 3D (AntiCheat only)**: the actual landscape and blocks coloured by kind, so houses, trees and walls look as they do in game.
- **See-through walls (AntiCheat only)**: a soft hole opens through walls and roofs between the camera and the watched player.
- **Hits and shots (AntiCheat only)**: players who get hit flash red, and shots (bullets, arrows) show as dashed lines. Anything flagged is red.
- **Alt alerts (AntiCheat only)**: AntiCheat warns staff when a banned player's alt account joins.
- **Stats prompt (AntiCheat only)**: AntiCheat asks once whether to share anonymous stats, as a card on its tab.

### For plugin developers
- New API for replays, prompts and linked accounts (API version 14). Get `hycon-api.jar` from https://github.com/Croc3ll/Hycon/releases/latest. You only need it to build plugins against Hycon; don't put it in `mods`.

### Changed
- Faster panel on slow connections: pages are compressed, so everything loads quicker.
- Big 3D replays load their blocks bit by bit, so they open fast.
- Saves and samples run on Hycon's own thread and never hold up the server.

### Fixed
- The panel slowed down in long sessions with replays open.
- 3D replays could stay flat.
- Replays didn't draw in 0.1.8.
- Replays showed an error in 0.1.16.
