- Call `_initialize` after tests have run
  Since the tests call `teardDown`, which removes all chatboxes.
- Open controlbox when navigating to panel

If configured for it.

Refactored the code a bit in the process.

* Remove some inline CSS style to improve CSP compatibility

* update changelog

This allows for cleaner separation between core and rosterview, making it
easier to remove that plugin for more stripped down deployments.

Similar to how backbone.js does it.

instead of having the ControlBoxView do it. This provides for cleaner
separation between the two plugins.

So that we can also fetch the roster also without the controlbox and rosterview.

When it's not possible to reconnect due to password no longer being cached,
render the login form.

Fixed a bug whereby after one failed reconnection event, reconnection becomes
impossible (due to 'connection' state of the controlbox).

Fall back to working version.
