Disable automatic ligatures display for specific language highlightings

[Andre601]

The paste service currently seems to apply ligatures to text, meaning displaying text like -> as → (Not accurate ligature... probably). The text itself remains the same, it's only visual.

However, this may still cause confusion if someone f.e. shares a configuration file, or an error and the text displayed does not represent the text actually used visually.

Ligatures shoudl honestly only be utilized in the [code] languages, which is what I would like to propose now. All other categories do not really have a need for ligatures to be used and may only cause general confusion for the people who read the paste, as it wouldn't represent what is actually used.
