Whenever we already deal with a User object, let's use the more specific
method avatar_icon_for_user.

Closes #40755.

Rearranged datetime created line

Added `avatar_class` option to `link_to_member` so it can be hidden

Made snippet title font heavier

Added file title  bar

Hidden unneeded info from xs screens

Added visibility icon

Reveal file-actions on xs screens

Added comments icon to snippets list items

Refactored no-comments declaration into framework stylesheet

Final touch ups

Fixed snippets_spec

* Introduce 2 color links: black and blue
* Use black color link for UI elements like lists
* Refactor lists to use .title nested under li
* Make all lists (events, todos, activity, projects etc) use style
* List colorschema is now 333 for links and 555 for text

 - Changed created_at to modified_at for snippets#index as it seems to
   be more relevant.

-Alt text to image was set to hash, which would make the page display hashes if the image/gravatar  wasn't available, set the alt text to '', and made the main tool bar image follow the same or similar constraints as the other images (.avatar, .s26)
