Describe your enhancement suggestion in more detail

In other source games, filtering out lines from console (to get rid of spam/find only meaningful error messages) is a bit troublesome as con_filter_text_out only lets you hide one string at a time. My proposal is to extend this command so that multiple strings can be passed in. There's a few ways this could be done, depending on performance impact (eg regex, reading from an external file, etc.)
