XdiMessagePatterns

XDI TC,

I turned the following page into an actual proposal:
https://wiki.oasis-open.org/xdi/XdiMessagePatterns

It does need some more work, but the basic structure is there.

It covers only the core idea of executing XDI messages and links to a lot of other proposals related to authentication, signatures, transactions, error handling, etc.

Also, it links to separate proposals for the specific operations ($get, $add, etc.):

https://wiki.oasis-open.org/xdi/AddOperation
https://wiki.oasis-open.org/xdi/GetOperation   <-- doesn't exist yet

https://wiki.oasis-open.org/xdi/ModOperation
https://wiki.oasis-open.org/xdi/DelOperation

I added them to the FrontPage under "Pages added or significantly updated this week".

I tried to apply the updated multiplicity syntax to all these pages, let me know if you find any bug.
