Prevent marking all torrents when changing location

[whiteout12]

Yesterday I had a little disaster that I think we could prevent from happening in the future.

I was about to change location for one torrent.
When having the modal for changing location in the foreground I pressed cmd + a to mark everything in the path box.
But I didn't realise the path box was not focused so instead all torrents got marked.
The rest I history an I moved all my torrents to the new location :(

Suggestion:

• Add a warning if more than one torrent is about to be moved
  or
• Prevent marking of all torrent when modal is up
