EFF DNT list unable to be activated/de-activated in 'trusted sites' panel

I tried to reproduce the issue when...

• AdNauseam is the only extension
• AdNauseam uses default lists and settings
• Using a new, unmodified browser profile

Description

EFF DNT list unable to be activated

I think the issue here is that when on the 'trusted sites' page, users don't know that the check-button is controlled only from the main settings page. So we just need some way to make this clear, could even just be a mouse-over

Added a tooltip to the checkbox: "EFF DNT Policy is automatically set if Non-tracking Ads are both NOT hidden and NOT clicked."
