Blocking Direct Access

Hey,

I guess this is a general notice, because in all my PHP files, everything is either a call to a built-in WordPress function, or the creation of a new function. So if you directly access one of the PHP files, the only thing that is going to happen is it’s going to throw an error because of an undefined WordPress function, or it’s going to do nothing because it’s just setting functions and not executing them.

Still, this can’t really hurt (except it increases the plugin’s size and running time by a tiny bit), so I guess I’ll include it in the next update. But I won’t push an update just for this, because it’s not a security issue in this plugin.
