Add option to handle "allowMultiple" extensions

Description

We have added a custom extension to Openfire, adding allowMultiple="true" to the stream header and/or adding it to the bind tags. Most likely this will only be used internally, but none-the-less, we need to add support to it into Whack so that Clearspace can make use of it.
