"Show in Finder" highlight bug

[Plecky]

I discovered a small UI glitch recently, where the "Show in Finder" button/icon is highlighted which I think should not happen, or only when pressed or mouseovered.

It just looks weird.

Steps to reproduce:

1. Select torrent in top half

2. Switch to Files or Peers info tab (not General)

3. Click anywhere in this tab to transfer focus from the selected torrent to the bottom tab

4. Switch to General tab. The icon is now highlighted.

To remove the highlight, select a torrent from the list or a category from the left.
