Fix 64bit Mac OS X w/ LuaJIT.

On my 64bit Mac OS X 10.9 machine, starting CorsixTH fails when
`luaL_newstate()` returns NULL, printing:

  Fatal error starting CorsixTH: Cannot open Lua state.

It turns out that 64bit LuaJIT on Mac OS X requires special linker flags, from http://luajit.org/install.html :

    If you're building a 64 bit application on OSX which links directly or indirectly against LuaJIT, you need to link your main executable with these flags:
        -pagezero_size 10000 -image_base 100000000

Fix:Ensures that patients won't fall through walls when they die

This commit fixes this issue:
http://code.google.com/p/corsix-th/issues/detail?id=947

It adds code to Die.lua:action_die_start to ensure that patients have enough space to fall over when they die.

It also adds a supporting function to World.lua which checks that a tile has no entity on it and (optionally) isn't in a room: World:isTileEmpty()

I've fixed the faulty Chewbacca fall death animation

The falling part of this animation is faulty with a missing heads layer in frame 30.
So this fix lets the first 21 standing transformation frames be played and then changes the animation to the standard male fall animation by using it as an extra east animation.
This fix also requires the saved game version to be incremented to 83.

The spawn animation function is now persisted

It wasn't persisted before because the comment
"[[persistable:idle_spawn_animation]]" was not on the same line as the
word: function.
