Merge remote-tracking branch 'upstream/master'

There are multiple hopper mods and not all of them support the set_extra_container_info function,
so the mod crashes now if it is used together with an incompatible hopper mod.

To prevent the crash, execute the code for hopper compatibility if hopper and hopper.set_extra_container_info exist and not if a mod named hopper is installed.

 TODO:
-* add abms when registering the chest instead of using chestdata
+* Fix open big chest back side texture: The current .obj mesh model uses a side
-* fix open big chest back side texture
