- Mesh update of node addition/removal is now done asynchronously on client, removing frametime spike
- Node addition/removal is sent directly only to clients that are closer than 100 nodes to the modification. For the others, the modified blocks are set unsent. (and are re-sent when applicable)
- Added better handling of textures. Now many file extensions are searched. Also too large textures are not put on the texture atlas, and the construction of the texture atlas is stopped when it is full.
