Allow append="merge" for (visual) inventory definitions
Right now to my knowledge, the only way to add 'modded blocks' to an inventory block, is to overwrite the full defenition in the modded block definition/mod of the particular storage container. This can potentially create conflicts when loading multiple mods that re-define the inventory items to allow support of their own modded items/blocks for the same storage container.
It would be neat and nicer if you could just append your blocks to the storage component, i.e. just expand the white-list and facade items to a storage block.
If this already would be possible, then I did not manage to get it working yet. Any advise then would be welcome ;-)
