Move initializing animals out of __init__ to global scope.

Before, having __init__ read from the filesystem was causing problems with
static compiling.

So I've just moved the initialization out of the __init__ function, and deleted the now-empty function entirely.

Per the julia docs, intializing an array like this doesn't need to be in
__init__ anway, the whole array can be serialized during precompilation.

Here's the relevant section (from Module-initialization-and-precompilation):

Constants involving most Julia objects that are not produced by ccall
do not need to be placed in init: their definitions can be
precompiled and loaded from the cached module image. This includes
complicated heap-allocated objects like arrays. However, any routine
that returns a raw pointer value must be called at runtime for
precompilation to work (Ptr objects will turn into null pointers
unless they are hidden inside an isbits object). This includes the
return values of the Julia functions cfunction and pointer.

Hey Mike,

Friendly ping! :) This should be a noop for your package, and will allow it to be statically compiled! :D

Cheers!

I should add that this is a follow-up to #77 which helped, but didn't solve the problem.
