Handling BTRoblox nav icons

[aubymori]

Is your feature request related to a problem? Please describe. The color of the BTR nav icons in the blue header are wrong.

Describe the feature you'd like I'd like these icons to be consistent with the 2016 style.

Additional context Go to line 1764 in the style, and add the .light-theme #header .btr-nav-notif selector to it. (Here's the CSS rule I'm talking about)

.light-theme .notification-red {
    background-color: #e2231a;
    color: #ffffff;
}

Also, add this CSS rule.

.light-theme .icon-nav-message-btr,
.light-theme .icon-nav-friend-btr {
    filter: none;
}

Thanks for creating a fix! It should now be in the unreleased style.
