Ability to disable "Joined the call" and "Ended the call" messages.

Describe the problem

My chat looks like this lol

Literally washes away any actual messages in the chat.

Describe the solution you'd like

Simple toggle in either the client settings or server wide (preferred) that disables these messages.
