Update emojis list to show positive intent first

What does this MR do and why?

This MR adds a simple MVC structure to sort emojis by positive intent first. The initial implementation makes it so :thumbsup*: and :slight_smile:/:slightly_smiling_face: appear first. It can easily be expanded to others.

This does not affect the initial list of emojis that are shown. It only affects the search results.
