Translate blocks

[snarfed]

When we first looked at blocks in #713, we concluded that the main effect of a block, on either side of the bridge, was handled natively within that network. The blocker would no longer see the blockee, and the blockee's interactions wouldn't reach the blocker. So, we didn't necessarily need to translate blocks.

This is true, but the blockee still gets to interact with the blocker's content on the blockee's side of the bridge. We can prevent that by translating blocks. We should do that!

Oh, that's surprising. I had (mis)interpreted the "just like with native users" in the docs to mean that the block would be visible to them too.
