Make status prompts and symbols more consistent

- Use status prompt “^_^” for emoji-table instead of “CN”
  The icon ibus-emoji.svg also looks similar.
- Use status prompt “Ć” instead of “C” for compose.txt
  Looks nicer, compose is about typing accents.
  It also looks more like the icon that way.
- Make sure that all tables have both status prompts and symbols
  (They can be the same always).
