Restore the Delete button when hovering threads in list

The Delete button (now replaced with an Archive button) while hovering a thread in the thread list should be reactivated.

Archiving sounds great and I’ll probably use it, but I’d use the Delete button way more often and I’d like it back. I’m fine with keeping the Archive button there too. I guess the reason you replaced it instead of just adding Archive is so that actions from that screen are undo-able, but I have delete-happy mentality formed pre-recycle-bin-OSes, consequences be damned!

If you should choose against it, I’ll suffer using the hotkey instead - just don’t take that away from me.
