Get rid of /clear command and keybind
Since the introduction of infinite scrolling, `/clear` is now broken. As far as I can tell, there is no way to reproduce something decent (and working!) without drastically changing its behavior from "hide the messages in current channel" to "permanently destroy all messages in memory in the current channel", which is not a great change to introduce sneakily 😂.

The code for this was very trivial, so removing it now until there is a better way to do so, if this is ever possible.

Also, `/clear` was not even autocompleted, sooo...
