feature request: discreet mode for the browser

[Danielshmaniel]

This could be added to the addon's menu, just like the other versions of this theme where you could use Discreet mode. Triggering Discreet mode would do the usual stuff like removing the blatant weebiness but keeping the colours, maybe even changing the addon icon. This, along with the previous thread about toggling new tab themes, would go hand in hand.
