Disconnect SSH connection when remote folder is removed

Clicking × on an SSH folder now calls liveDisconnect + liveRemove on
the connection that was created for it, freeing the slot and closing
the SSH session. The connectionId is threaded through addSshFolderToPanel
and stored on FolderState. Folders using an already-active connection
(no connectionId) are unaffected.
