add the part-handler plugin

If a part of a multipart file is 'text/part-handler' then it is 
expected to be python code that implements 2 methods

- list_types()
  list the types that this part-handler supports, return
  a list.  ie: return(['text/plain'])

- handle_parts(data,ctype,filename,payload)
  this method will be called:
     once, when loaded, with ctype == '__begin__'
     once per part
     once, at the end, with ctype == '__end__'

   - ctype is the content type ('text/plain')
   - filename is the filename portion of the mime data
   - payload is the content of the part
   - data is currently the cloud object, but this could change
