Adds autocomplete for tagging topics.
- Recommendation algorithm is very basic, just gets the most commonly used tags in this group that start with the letters that have already be typed. Doesn't have any fuzzy search or edit-distance or anything, I feel like those can be easily added on after?
- Not sure about the best way to keep the suggestion dropdown visible, since the input is at the bottom of the page. Making the page taller for now, but the dropdown covers the post topic button. Let me know what you think. (you can 'Escape' to close the dropdown).
