In this update a lot of novelty, and bug patch

News :
A new inventory for the brush flower,
- You can now drop off your blocks/items (no need to choose from the flower list)
- You can now modify block / item properties

The inventory for the organic humanoid spawner has also undergone some changes,
- you can now pregenerate and generate the organic from the inventory via 2 new buttons

New brushes are appearing:
- Discover the Brush Eraser to clean your land,
- Or the addition of the erode melt, lift, fill terraforming brushes, and the ErodeBlend argument

- The 2 default tools for terrafoming are now the SPECTRAL_ARROW and the CLAY_BALL

-The /tool command now gives the plugin's terraforming tools rather than those of voxelsniper

If you have an old version of ExpertBuild, I strongly advise you to delete the config.yml file, so that the pplugin can recreate a clean file for you.

Fix bug :

- The pregen and the generation did not take into account the members set to false,
- Set position messages were not sent to the player every time
- The brush sphere was out of order
- The command /convertslab (convert double slabs to block) only worked on wood
- The coloring in the inventory of custom leather does not accept being at 0
- Security update of FAWE API to version 2.6.3
