Don't display interaction buttons on timelines by default

[pwd-github]

Consider only displaying the buttons under each toot only when a user actually wants to interact with said toot.

Having checked, I think this is a dupe of #1163

[Lakoja]

Yes.

While #1163 could probably closed as well (normally posts are larger than only a few lines, so this feature doesn't make much space saving).
