Add support for substitutnion (s/expression/replacement/)

[roket1428]

What do you want

Allow s/expression/replacement/ syntax in text input mode.

Why

Because vanilla React Discord App supports it.

Implementation hints

You can pretty much try and see the result by testing the React client. But it just substitutes the last message of yours with an expression.

I personally have no interest in this feature and don't deem it to be very useful, therefore I won't work on it, but I'd accept a pullrequest.

Fair enough but if you are trying to make Cordless "like" Discord, it is a default behavior.

I am not trying that to such a degree ;)
