Better discoverability in content record sidebars

It was a bit difficult to find where your sidebar plugins ended up in the content record sidebars.

Earlier, you had to open the sidebar, find the little downward pointing arrow and then switch to the view that plugin offered.

It caused a lot of issues for many of you, and wasn't really the best UX, so we've improved it.

Now, simply open the sidebar if its collapsed, and you'll see a tab for each of your sidebar plugins neatly next to one another.
