/**
* @brief Hooks the function to a specific pilot.
*
* You can hook to different actions. Curently hook system only supports:<br />
* <ul>
* <li> "death" : triggered when pilot dies (before marked as dead). <br />
* <li> "exploded" : triggered when pilot has died and the final explosion has begun. <br />
* <li> "board" : triggered when pilot is boarded.<br />
* <li> "disable" : triggered when pilot is disabled (with disable set).<br />
* <li> "jump" : triggered when pilot jumps to hyperspace (before he actually jumps out).<br />
* <li> "hail" : triggered when pilot is hailed.<br />
* <li> "land" : triggered when pilot is landing (right when starting land descent).<br />
* <li> "attacked" : triggered when the pilot is attacked. <br />
* <li> "idle" : triggered when the pilot becomes idle in manual control.<br />
* </ul>
* <br />
* If you pass nil as pilot, it will set it as a global hook that will jump for all pilots.<br />
* <br />
* DO NOT DO UNSAFE THINGS IN PILOT HOOKS. THIS MEANS STUFF LIKE player.teleport(). IF YOU HAVE DOUBTS USE A "safe" HOOK.<br />
* <br />
* These hooks all pass the pilot triggering the hook as a parameter, so they should have the structure of:<br />
* <br />
* function my_hook( pilot, arg )<br />
* end<br />
* <br />
* The combat hooks also pass the pilot acting on it, so for example the pilot
* that disabled, attacked or killed the selected pilot. They have the
* following format:<br />
* <br />
* function combat_hook( pilot, attacker, arg )<br />
* end<br />
* <br />
* Please note that in the case of disable or death hook the attacker may be nil
* indicating that it was killed by other means like for example the shockwave
* of a dying ship or nebula volatility.
*
* @luaparam pilot Pilot identifier to hook (or nil for all).
* @luaparam type One of the supported hook types.
* @luaparam funcname Name of function to run when hook is triggered.
* @luaparam arg Argument to pass to hook.
* @luareturn Hook identifier.
