[Zope] Determining object type

[Phil Harris]

meta_type is not always a simple type (i.e. string).  if you do if meta_type
== 'Folder' for instance it will fail, since meta_type for a folder is a
method.

using _.getitem returns a string, i.e. it renders it so to speak.

but I may always be talking out of my jacksee of course ;)
