Messages with body and subject are processed as attempts to change the room subject

Description

http://www.igniterealtime.org/community/message/157615#157615

We should do the following:

"The subject is changed by sending a message of type "groupchat" to the <room@service>, containing no body but a <subject/> that specifies the new subject"

therefore we should treat these messages as broadcasts to the room.
