pets get their action bar, macros arrive, and hunters draw the bow

- a hunter's or warlock's pet has its action bar now: attack, follow, stay, the pet's own spells with cooldowns and autocast sparkles
- the macro system lands: the macro window, the icon chooser, /cast and /macro, and macros dragged onto the action bar
- hunter shots look right at last: the bow draws and releases on the shot, and the arrow lays a spark trail its whole flight
- the options window re-dresses in 1.12's own art with the classic dialog look, and gets a working search box and clickable steppers
