Light theme color is off from other (native) icons in URL bar

[quassy]

Steps to reproduce

1. Visit a page that has a rss feed
2. Compare the shade of grey of awesome rss and other native toolbar buttons

Expected behavior

The subscribe button should look native and have the same shade of grey.

Actual behavior

The subscribe button for light theme is brighter #7F7F80 than other buttons like star #666666 in the URL bar.

I believe there are two different shades of grey depending on whether the icon is shown in the URL bar or in the ellipsis menu.

Screenshots and/or logs (see how to open the developer console in your browser)

@quassy I guess they changed this on me. I'm using the actual Photon icon, and I guess I need to do some updates to keep up.

The fix looks fine for the address bar.

Unfortunately, Firefox uses a different color in the ellipsis menu than in the address bar, so there your icon is too bright now. 🙈

@quassy I'm not aware of any way of distinguishing between display in the address bar and in the menu. I'll review other add-ons to see if/how they do this.
