Adoa's Minimap

Added
- a /minimap diagnostics command that allows the owner of the server to see specific diagnostics of each player at once, or all of them together.

Fixed
- the name space. (reverted to 

- Delayed/laggy minimap after going through a portal. 

- Map markers ignored the Detail/zoom setting. Spawn/bed markers were placed

  with a fixed scale that didn't include the zoom factor, so they drifted out of

  place at anything other than one zoom level. They now use the live

  pixels-per-block, so they track the terrain at every Detail level.

- Crossing a chunk boundary could upload several new tile textures to the GPU in a single frame. Those uploads are now spread across a few ticks, so a burst no longer freezes a frame.
Be aware: Turning on Waila, Enemies and map markers is a heavy task and can still cause unexpected lagg.

- Enemies are now drawn as lightweight in-place UI dots (coloured per the Enemy colour setting

Changed

- Update Rate range and default. The slider now runs 100–1000 ms (was 50–500);

  the floor is 100 ms because below that the per-update client work causes lag

  spikes. New default is 1000 ms

- Map fills in faster after a jump. The number of tiles applied per update now

  scales with the Update Rate

- Lighter default scan interval, now 500 ms

- Existing players keep their own saved Update Rate / Sharpness / Scan Interval;

  the new defaults apply to new players (and any value below the 100 ms floor is

  raised on load).
