Support helm-ls-git

[duianto]

https://github.com/emacs-helm/helm-ls-git has two default colors that cause issues with the Spacemacs themes.

The faces are shown with colors in: M-x helm-apropos
search for: helm ls
press: M-o (it calls: helm-previous-source) to scroll to the last source: Faces

spacemacs-dark

The blue face: helm-ls-git-added-modified-face is hard to read.

spacemacs-light

The yellow face: helm-ls-git-modified-not-staged-face is to close to the bright background.

It looks like this in the M-x helm-ls-git-ls buffer

Spacemacs develop

In Spacemacs the helm-ls-git-ls buffer can be accessed with: SPC g f f
And helm-apropos with: SPC h d a
There's also helm-colors: SPC C l (l = lowercase L)
