Another silly hack

I've been using snapshots of emacs 22 and i've noticed that emacslient
now supports the injection of arbitrary elisp expressions into the
current emacs instance, as a quick hack i've implemented a cite_emacs
method on the Document object based on cite_lyx to insert citations into
the current cursor position in the current emacs buffer. 

I assume that emacs is already running the emacs server (M-x
server-start) 

The hack works by: 
 making a latex citation string (\cite{xxx,xxx,xxx}) 
 writing it into a temporary file and then invoking emacsclient -e
'(insert-file tmpfile)'
 deleting the temporary file. 

The method is attached, but this isn't supposed to be a proper patch as
it is not particularly robust and  has a number of problems (not least
hanging on the invocation of emacslient when the command fails).  It
might however form the basis for something in a future version(for
people who don't use kile or lyx).
