YASnippet isn't loaded for CSS/SCSS modes and can't find .emacs.d/private/snippets dir

[ashervb]

Opening a CSS or SCSS file doesn't enable YaSnippet mode.

In my attempt to load them, I performed M-x yas-global-mode. This causes emacs to attempt to load from .emacs.d/snippets rather than the .emacs.d/private/snippets dir. Putting snippets in the former dir allows them to be loaded. Not sure if these issues are related. Note that it DOES find .emacs.d/private/snippets on non CSS/SCSS files.

That's because the hook that sets up spacemacs's yasnippet snippets is only added to certain parent modes:

(add-to-hooks 'spacemacs/load-yasnippet '(prog-mode-hook
                                          markdown-mode-hook
                                          org-mode-hook))

css-mode and scss mode do not inherit from any of the above top-level mode classes. They both are derived from fundamental-mode, so the hook should probably be added to them individually. I have also noticed that snippets aren't loaded for latex mode sometimes, since it derives from text-mode.
