fix: if fullname does not exist, an exception will report about *split* ...

Make sure the last roster item is still added (even if it's a zombie), so that
the roster will be shown (roster is only shown when last_item property is
true).

It's a relic from a time before the class subclassed a Backbone.Collection

When using show_only_online_users, roster item DOM elements are removed from
the DOM if their status changed from 'online' to something else.

When their status changed to 'online' again, they were re-added.

Their views (RosterItemView) instances however didn't listen to events anymore.

Calling delegateEvents on the view after calling $.remove() fixed this.

Instead we build manually. Fixed paths in build.js

If true, only users with a status of 'online' will be shown in the contacts
roster.

Move all module-level functions/variables and Backbone Modules/Views together.
Add headings to indicate logical sections.
Make statuses variable module-level and indicate that it's a constant (all caps)

This method shouldn't be called when contact requests aren't allowed because
roster items are then not created for contact requests.

- Register handlers that depend on the roster inside initRoster and the
  message handler inside chatboxes.onConnected. This solves problem of presence
  stanzas being received before handlers are initialized. Updates #65

- Check if MUC is allowed during feature discovery
