HttpAdapter class JAASification

Hi,

I had to modify the mx4j.adaptor.http.HttpAdapter class for my project so that users can authenticate
against JAAS login modules instead of the regular username/password
method provided ( addAuthorization( String userName, String password ) {...} )

I've done this for the 1.1.1 version, let me know if you would like to see
such functionality with the latest CVS HEAD version of the file.
I could do the CVS patch quite quickly.

Regards
