Users without roster contacts didn't have XMPPStatus.initStatus called and
therefore had a default status of offline.

Fixed this by setting the status to online from the start. The fetch command
will get the true status from localStorage (if available).

Made sure that the rest of converse's onConnected code is called in the
callback from fetch (so that we know the user's status is correct).

Updated and fixed tests.

On Plone I've been having issues with event handlers being registered on
elements not yet added to the DOM not being called.

Also, get rid of the misnamed $parent attribute on the panels. Instead, pass in
the correct parent to initialize.

otherwise the optimizer doesn't include it

With jquery  > 1.8.3, $(window).trigger('focus') doesn't trigger the handler.
Manually focusing the window does however trigger the handler.

- it calls 'bower update' and then 'make normal' inside the strophe dir.

This should make it easier to create custom builds, e.g. with more or less
dependencies.

- Also added bower.json with all 3rd party dependencies specified
- And .bowerrc to specify components dir

I added them for someone who promised hu translations, but they are now just
taking up space.

- Removed phantom-jasmine, not used.
- Updated CONTRIBUTING.rst
