Add CORS headers to HTTP-Binding/BOSH

It seems that CORS headers are not set at all for 3.8.2 although I have enabled support for CORS in the admin panel:

Request Headers
Accept /
Accept-Encoding gzip, deflate
Accept-Language pl,en-gb;q=0.8,en-us;q=0.5,en;q=0.3
Content-Type text/plain
Host myserver:7070
Origin http://myserver
Referer http://myserver/converse.js-0.6.4/chat.html
User-Agent Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0

Response Headers
Accept-Ranges bytes
Content-Length 222
Content-Type text/html

Updated HttpBindServlet to return CORS headers for all HTTP responses (including errors) if CORS is active.

That's great!

Thank you.

I am working on the BOSH components for another issue (), so I will take a stab at this one as well.

I've reopened the issue
