Breaking changes

MimePowersComponent and MimePowersSystem have been moved to the Content.Shared.Abilities.Mime namespace.

The invisible wall action needs the popups predicted.
Same for the spawn of the invisible wall.
And dirty the component when you change its datafields.
Also you can set SendOnlyToOwner in the component to true because other clients don't need the component. Not really that critical if cheat clients can see it, but it's also a performance improvement.

Same for the spawn of the invisible wall.

Wait, predicted spawning is really so necessary for invisible wall? Because it's pretty invisible and feels only on collide and the moving is pretty unpredicted.

I guess it's not completely needed, but doesn't hurt either. It makes sure you can't put any items into that location if you are lagging.

I pushed some more cleanup changes.
Thank you for your contribution!

I thought that we don't change "namespaces()" to "namespaces;" to get less merge conflicts in the forks.

[slarticodefast]

We were moving the file anyways, so I would say it's fine in this case.
