[3.4.1] Bug fix for the '/tgconfig toggle updatechecker' command:

• Would only toggle the config setting once per restart/reload. Fixed it so that it works like the rest of the /tgconfig commands. The plugin reload and config value change should happen immediately.

Also, I set the default value for the update checker config setting to false. Will have to turn it on in game now.

Sorry about that! Let me know if you guys find any more bugs, thanks!
