Way to implement Auto-attack

[Kira75]

make auto attack optional, win win.

While I know many probably want auto-attack, I know some like myself would prefer to have control over ones actions. More specifically on a class like Archer where your attacks aren't free. Making this optional seems like the best option, turn it on when u need or want it, turn it off when you don't. Preferably I would never turn it on myself though, as I like to control my character continuously, more to do, less staring and watching.
