Implementation detail

I considered 2 approaches for this:

1. Initially I considered passing all of the text-to-emoji mappings and have all the logic on the rust side to do the replacement when the text changes. The advantage to this is that it maximises code re-use on the rust side.
2. Then I considered extending the Suggestions api(that slash commands and mentions are built upon) to support "custom" suggestion patterns(in addition to the existing static ones /,@, #). The advantage of this is that it builds upon an existing pattern rather than creating a new way of doing things. It also gives flexibility to the client as to how the feature works. The version implemented works as the web-client does, by automatically replacing the suggestions, but there has been a suggestion previously that it should work as it does on Telegram where suggestions are rendered first from which the user can choose to accept:
