Review multiple file post - is the api robustly handling multi-file uploads

[GoogleCodeExporter]

Currently the app splits multiple file uploads into a collection of single 
uploads and duplicates shared settings (journal name, entry, tags, etc). 

The api checks (on each upload - rather than just ones known to be multiples ;) 
if a duplicate post (by title/entry) already exists. If one does then the 
uploaded file is attached to the existing entry.

a) ideally pass additional (Part) and (Count) parameters in the post if the 
entry is part of a multiple upload. 

b) the api should if (Part) check for existing Journal post with provided 
details.

c) The api should not check if (Part) not provided - reducing load.
