MSRP support

[GoogleCodeExporter]

Does boghe currently support MSRP protocol for chat and file transfer? Which 
server can it be tested against? Tried it with sip2sip.info account and it does 
not work, while Blink client (http://icanblink.com) works fine. sip2sip.info 
provides support for MSRP protocol via MSRPRelay server (http://msrprelay.org) 
- can boghe work with it?

What steps will reproduce the problem?
1. Sign in for two sip2sip.info accounts in two instances of boghe.
2. Try to send messages via chat or send files. It does not work, while simple 
chat (sms) works.

What is the expected output? What do you see instead?
Messages and files are not sent, as expected, since sip2sip.info supports MSRP.

What version of the product are you using? On what operating system?
Latest version 2.0.113.744, tried on Windows XP and 7. As far as I can see 
while debugging  - it does not try to send AUTH request to MSRP server.

Please provide any additional information below.
If boghe does not support MSRP for chat and file transfer, when what protocol 
does it support and how can it be tested, with what server?
