Amulet-map-editor

Added importing and exporting of the Sponge Schematic format.
Added drag and drop importing.
Simplified the import tool.

Fixed some issues with height and light values.
Fixed some issues with leveldb for some Windows users.
Fixed the set biome tool not being listed.
Cached texture atlas so loading should be a little faster.
Fixed a render issue causing the world to be upside down.

Improved language support for similar languages. If languages with different regions are similar enough, they can share a lang file without the region extension and the region specific file can just contain the translations that are different.
Hopefully fixed some more OpenGL issues.
Cleaned up the built release to remove the unused source code.
minecraft:cave_air is now treated like normal air in the 3D editor.
Fixed some issues with the selection being unpredictable.
Improved the paste tool to bring it in line with how it behaved before the recent rewrites.

Previously all the source code was distributed the program and in some places it was run from the source and others it was run from code within the executable. This build should have cleaned that all up so it is all run from the executable.
Custom user extensions will still be run from the source.

Added:
- Added a more visual selection box (please give feedback and improved colour palettes)
- Updated leveldb library
- Partial localisation for Chinese, French and German
- Hopefully added support for older hardware that do not support OpenGL 3
- Support for the Bedrock v22 chunk

Fixed
- Improved thread safety of the chunk mananger
- Improved chunk loading to better support modded and new data.
- Added better error messages for world loading
- Fixed the box inputs not updating in the select tool

This is a build to test support for OpenGL 2.1
