[sr-dev] Presence_profile documentation

http://kamailio.org/docs/modules/3.3.x/modules_k/presence_profile.html From reading this documentation I can't figure out anything on how to use this great and cool (I hope) new module. I suggest that the author not only correct the spelling of his name (because I don't believe the HTML representation is correct) but also give some usage examples. Add some examples on how to update the presence status, the model for usage and configuration issues. I think UA-config is important, so we might as well add a bit of information from the RFC to educate our users. Thanks for adding this module! /O
