Xaero's Minimap

* Compatible with Xaero's World Map 1.11.0 or newer. Version 1.12.0.2 is recommended.
+ Added 3D slope shading, which now also takes horisontal slopes into account. The old 2D shading (vertical only) is available as an option in "Terrain Slopes" as "Default 2D".
* Reduced the number of possible slope colors because I think it looks better. Doesn't affect most of the map.
* Fixed entity icons causing a significant lag spike on first render.
* Optimized minimap and chunk grid rendering.
* Improved empty entity icon detection. For example, custom models/animations (Optifine resource packs) that break the original entity models, causing the icons to become invisible, will now be detected. Dots will be rendered instead.
* Added brightness-dependent opacity to the chunk grid, so that the actual map is easier to see at night.
* Increased the brightness range of darkened entities.
* When in cave mode, entities should now change transparency based on your Y-distance instead of brightness.
* Fixed the huge offset of the displayed name for entity icons that defaulted to dots.
+ Added a new setting for changing the UI scale of the minimap. The default "Auto" option should work the same way older minimap versions did. This isn't perfect yet because it literally just scales everything up/down without affecting how much is visible. I want to fix that in the future.
* Fixed crash when certain modded entities fail to render for the icon/head.
* Some controls code clean up.
* Fixed symlink support in a lot of places.
