called by: Cheetah.Template.__init__()

Same as os.makedirs (mkdir 'path' and all missing parent directories)
but also puts a Python '__init__.py' file in every directory it
creates.  Does nothing (without creating an '__init__.py' file) if the
directory already exists.

Save as list_.remove(each element) but don't raise an error if
element is missing.  Modifies 'list_' in place!  Returns None.

Raise 'thing' if it's a subclass of Exception.  Otherwise return it.
