Update the entities as soon as mapblock is loaded

Useful e.g. after /clearobjects Introduces the group display_lib_sign

Very good idea and a last, it solves the /clearobjects issue :+1:

I have a remark, this is not only a signs stuff, this should apply also to clocks and steles.

So the group should be named something like "display_lib_entity" instead of "display_lib_sign" and added to clock and steles nodes.

Thanks for your answer!

I added the group to clocks and steles now, too. I decided to use the group name display_lib_node. I hope this is ok for you.

[Thomas--S]

Updated once again because there was still one little mistake left. (Steles were not updated correctly.)

Now it should work fine.

[pyrollo]

Yes, that's fine, I was hesitating with this name also :)

Thanks for merging!
