[dev] More MIME improvements

OK - I had to reconfigure the MIME parsing system so that we will be able 
to correctly identify and parse PGP messages using the MIME_Viewer 
framework.  The problem with the current system is that none of the 
information about groups of MIME Parts (i.e. the header information for a 
group of MIME parts labeled 1.1, 1.2, 1.3, etc.) was parsed out of the MIME 
headers.  This is crucial since under RFC 2015 the PGP message 
identification appears in these headers - these are the headers needed to 
call the correct MIME_Viewer.

This functionality has been implemented now.  Let me know if you want gory 
details about what the data structure changed to: for starters, I have 
printed a sample output using print_r() for a multipart message using the 
new and old functions at:

http://bigworm.colorado.edu/imp-patches/pgp/mime_old.txt

(BTW, just to make sure I haven't screwed anything up, I ran a test using 
the MIME torture test that comes with UW-IMAP. Everything worked fine.)

However, I haven't altered the PGP MIME_Viewer yet so nothing will appear.  
Here's a quick patch that will, until I fully implement, just print out the 
contents of a PGP message to the screen.

let me know if you have any questions.
