Feature: allowing include to accept directories

[lorensr]

I'm currently getting a strange error and am hoping you might know what it is?

$ cat test.coffee
require('zappa/src/zappa') ->  
  include 'db'
$ ls db
model.coffee 
setup.coffee
$ coffee test.coffee

Does this call have to by synchronous to make sure that all the pieces are loaded in a predictable order? I'm curious about potential race conditions that may result from the unpredictable callback execution order.

I changed it to

  root_locals.include = (name) ->
    if fs.statSync(name)?.isDirectory()
      for file in fs.readdirSync(name) when not is_tempfile file
        root_locals.include name + '/' + file
    else
      root_locals.include_file name

and the slightly different output I'm getting is
