Added the ability to bind atcommands to NPC events (ex: NPCNAME::OnEvent); original version by ToastOfDoom however heavily modified by I enabling command level at the invoking/character (@/#) level and fixes to prevent console errors as well as fixes aimed to ensure compatibility with rAthena.

Updated the script_commands.txt documentation with the following script commands: bindatcmd, unbindatcmd and useatcmd.
