Now that standalone contact adding works

It depended on triggering events for which we've removed the handlers

- Removed the $(document).ready handler. Instead, converse.initialize must be
  called manually together with settings data.
- As a result the Plone specific event listeners are now also gone.
- Update tests and index.html to deal wit these changes

And a file with some preliminary notes

New conf variable in converse.js to indicate how contacts are added (either via
XHR or directly).

Controlbox's status widget was being overwritten

The chat toggle element is now determined by class, not id.

Add empty specs for status widget
Fixed roster localStorage spec to not break the xmppstatus view

Truncate pending contacts with too long names
Position accept/decline buttons below pending contact's name

which after being fixed removes the need for the sleep() command because you
can set the execution speed via jasmine's updateInterval attr

Inside this method we can then check if animations are turned on.

Rather than calling remove and triggering a custom event

So that we have test suites for each type of contact
- Pending
- Existing
- Requesting
