Remove chat feature

This was originally contributed upstream by Stanford, circa 2013.

We neither use nor support this feature in its current implementation,
and in fact, we may never have used this production. Until recently, we
had additional chat/Jabber code [1] (in the form of a Jabber djangoapp in
LMS); context there suggests this feature may have never been more than
a prototype. The original author is no longer on the team, so I can't directly
confirm this on our end.

Do you use this feature?

Stanford had already abandoned this Jabber-backed chat implementation,
in favor of an IRC backend, by the time I joined the team in early 2014.

- *  This extension already exists in some browsers (namely, Firefox 3), but

- *
- *  Parameters:
- *    (Object) obj - The object that will become 'this' in the bound function.

-/** Class: Strophe.Builder
- *  XML DOM builder.
- *
- *  This object provides an interface similar to JQuery but for building
- *  DOM element easily and rapidly.  All the functions except for toString()
- *  and tree() return the object, so calls can be chained.  Here's an
- *  example using the $iq() builder helper.
- *  > $iq({to: 'you', from: 'me', type: 'get', id: '1'})
- *  >     .c('query', {xmlns: 'strophe:example'})
- *  >     .c('example')
- *  >     .toString()
- *  The above generates this XML fragment
- *  > <iq to='you' from='me' type='get' id='1'>
- *  >   <query xmlns='strophe:example'>
- *  >     <example/>
- *  >   </query>
- *  > </iq>
- *  The corresponding DOM manipulations to get a similar fragment would be
- *  a lot more tedious and probably involve several helper variables.
- *
- *  Since adding children makes new operations operate on the child, up()
- *  is provided to traverse up the tree.  To add two children, do
- *  > builder.c('child1', ...).up().c('child2', ...)
- *  The next operation on the Builder will be relative to the second child.
