Hook Control Plugin

The hook control plugin allows an admin to turn off or on the ability for everyone to 
use the grapling hook.  Displays message in the center of the screen
that says either "The hook has been turned off" or "The hook has been turned on".  
A voice over also announces "magnetic systems deactivated" or "magnetic systems activated"
after the command is executed.  Really quite cool.

Commands:
"admin_hook off" == disables the hook
"admin_hook on" == enables the hook
