https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/1210 disabled
autocomplete for personal snippets and project snippets. But we want
autocomplete on project snippets.

Fix https://gitlab.com/gitlab-org/gitlab-ce/issues/33594

Was supposedly fixed in MR for
https://gitlab.com/gitlab-org/gitlab-ce/issues/32086 but seeing this pop
up again

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

This reverts commit 3e991230.

Closes #14328

Closes #3701

Also fixed an accidental deletion of pratial

Split out header into shared partial
Used action partials to have unique actions for shared and personal
snippets
changed back to created date in list view
Switched to using existing color classes

write_ was renamed to create_
modify_  was renamed to update_

So now in update action we have next code

def create
  can?(current_user, :create_issue, @issue)
end

def update
  can?(current_user, :update_issue, @issue)
end
