SIMPLE chat: Internationalization and normalization of nicknames

Dear all:

I am trying to address the last known issue of the SIMPLE chat draft. 
This came through Enrico Marocco's Appsdir review, and the comment was:

The document doesn't describe allowed characters in Nicks and any
normalization that needs to be applied.

So, I got advice from Alexy Melnikov, indicating that we should take a 
look at the ResourcePrep in:
http://datatracker.ietf.org/doc/draft-ietf-xmpp-6122bis/

The idea is to inspire on the ResourcePrep and adapted to Nicknames in 
SIMPLE chat. However, there is a dependency on the completion of the 
Precis Framework:
https://datatracker.ietf.org/doc/draft-ietf-precis-framework/

This means that SIMPLE chat will need to add a normative dependency to 
the Precis Framework, and if SIMPLE chat is approved and arrives to the 
RFC Editor before the Precis Framework, it will stay there until the 
framework reaches the RFC editor.

I guess this is what we should do, but if someone has any other opinion, 
please let me know it.

The internationalization and normalization of nicknames will probably 
take a bit of my time until we do it. So, I propose to submit my current 
working copy, that contains all comments from Cullen, Christer, Saul, 
Suresh, etc. This will be version -14.

Comments, please?

/Miguel
