Active buffer tab background color

[towry]

The current active buffer tab background color is confused

I always thought the bright one is the current, active tab, it's confusing.

So I modify the source to change it to like this:

Now the bright one is the current.

Hi @towry.
This issue was related to vim-buftabline plugin which made some custom highlighting.
I've modified it to match the current gruvbox airline buftabline colors.
