Chat autocomplete

This mod allows faster typing and less typos in the minecraft chat with an adaptive Markov chain algorithym that learns communication patterns. The autocomplete might feel stupid at first, but as it gets more data, it should get better. The only language supported for now is english. There is currently no autocorrect function, but there could in future versions.

IMPORTANT: The Markov chain function could save entire messages from players through the chat. That localy saved data is used ONLY for a better user experience and will NEVER be shared. The saved contents can be found in the minecraft config files at _autocomplete_markov.json_. Note that the file could end up bigger than a MB of storage if the mod is used for a long time.
