Add support for other blocks with inventory

[Fixer-007]

For example:

• technic chests
• drawers
• more chests
• mcl chests
• homedecor containers
• bookshelf/vessels
• etc (all of them above as optional dependencies)

But maybe there is a way to interact with any block that has an inventory, that will simplify things a lot without needing to add support for each mod.

• technic chests: already supported
• drawers: Drawers probably don't use inventories to store items, so this wouldn't be easy to supported
• more chests: This chests are too special to support them.
• bookshelf/vessels: probably not because you can't store all items types in those.
• homedecor containers: Does anyone use these to store items?
• mcl chests: This mod was made for the default minetest game but I will consider that.

But maybe there is a way to interact with any block that has an inventory, that will simplify things a lot without needing to add support for each mod.

This is a very bad idea, because not every inventory is used to store items.

homedecor containers

homedecor has locked/unlocked furniture with inventories (fridge, cabinets, etc)

Does anyone use these to store items?

Yes, I've seen it on some servers with homedecor. But I'm not really sure if someone will hook up storage interface to furniture...
