Changes in this update:

- Fixed some incorrect disconnect messages.
- Blocked an exploit that could be used to crash servers.
- Added a Mulitplayer Option to disable sprays to prevent other players' sprays from appearing on your client.
- Temp files are removed from disk after each session. Use "l4d_delete_temp_files 0" to disable this.

An update next week will contain a change that clears temp directories when you exit the game. This will delete any spray files that have been downloaded from other players during the session. If you do not want your temp files to be deleted, you can set "l4d_delete_temp_files 0" to disable it. In the meantime, if you're really attached to your spray collection, you may want to copy them somewhere safe now in case you forget to set the convar next week.
