Description

Related to #1832
For example, if I had basic sm_play access as a moderator, and there were no immunity checks on targetting higher admins, I would be able to run !play <target> "\";sm_ban boink 0 reason", and the plugin would be running both playgamesound and sm_ban as two individual commands through ClientCommand(""), on the targetted player.

Problematic Code (or Steps to Reproduce)

!play Dolly "";sm_slay Rushaway"

The empty "" is to do not specify any files to play
