Add option to escape colour/formatting codes

Sorry to ignore the Feature request template but it's clearly more for suggesting improvements rather than asking for actual features to be added.

My idea is to add a way to escape colour and formatting codes in holograms and similar to just show the text. A small example: I have the text Use "&[colour]&s" to add a shine effect to your message. set in the hologram. Now instead of formatting it to have the text after &s contain the shine effect, it would stay the same and just show it as I wrote it (maybe with using a \ before the &?)
